(Note - I didn't use 'will' anywhere in my answer. Hope you're happy, but I don't understand why using the word 'will' was such a big problem)
It's a problem to use language like 'will' because it implies that something is definitely going to occur as a consequence of legalising SSM, which you of course can't be sure of.
- This limits freedom of speech, as you cannot say that you disagree with something for fear of being shut down...and criminally prosecuted, and possibly thrown in jail
Except it doesn't, because legislating for SSM doesn't simultaneously mean that people who express opposing views are liable to be 'thrown in jail' (we're still just talking about SSM at this point in your explanation). Of course everyone will still have the freedom to hold those views, just as others will have the freedom to judge people based on whether or not they disagree, and again there's no legal limitation placed on people expressing their opinion.
If you're arguing that people will just feel like they don't want to say they don't like SSM because of possible backlash from those around them, then that's just a product of society progressing. I'm sure people who were against interracial marriage (or the abolition of slavery, or women voting etc etc) felt like they didn't want to express opposing views after it was changed, but we can't just not have any societal change ever because of the feelings of people who hold the minority view.
- With same sex marriage out of the way, the left will attempt to find something else to fight against, and as is the case with Canada, they are likely to turn to transgenderism issues
I'll put forward my arguments against the rest of your points below, however arguing that 'the left' moves from one social issue to the next collectively, and that the legalisation of SSM will also lead to the enactment of other laws relating to transgender issues without further debate within society (as if they aren't being debated right now, and wouldn't continue to be debated in the future regardless of the outcome of this postal survey), seems like a pretty disingenuous slippery slope.
- As a result of these new transgenderism laws, people who disagree with transgenderism are unable to voice their opinions as they are once again the minority and are outsiders...it is not irrational to conclude that transgenderism is treated differently to SSM...so people are, again, criminally prosecuted, fined, and maybe even thrown in jail.
Reading into one of the 'new transgenderism laws' that you brought up (C-16) led me to the Canadian Bar Association's response to it, which can be found here:
https://www.cba.org/News-Media/News/2017/May/CBA-position-on-Bill-C-16. In it they argue:
"Recently, the debate has turned to whether the amendments will force individuals to embrace concepts, even use pronouns, which they find objectionable. This is a misunderstanding of human rights and hate crimes legislation."
On the debate as a whole being shut down if the law was enacted, the CBA cites the Supreme Court of Canada (Saskatchewan (Human Rights Commission) v. Whatcott):
"The distinction between the expression of repugnant ideas and expression which exposes groups to hatred is crucial to understanding the proper application of hate speech prohibitions. Hate speech legislation is not aimed at discouraging repugnant or offensive ideas. It does not, for example, prohibit expression which debates the merits of reducing the rights of vulnerable groups in society. It only restricts the use of expression exposing them to hatred as a part of that debate. It does not target the ideas, but their mode of expression in public and the effect that this mode of expression may have."
On the other law from NYC, you seem to ignore the use of words such as "
repeatedly referring to a person.." or "
refusing to call a person..." when you argue that "it is extremely difficult to prove whether someone was intentionally discriminating or accidentally discriminating against a transgender person, hence the danger of this law. But even if it was an 'ordinary violation', meaning accidental, you can say goodbye to $125,000". The law is clearly designed to protect individuals from
continual harassment based on their gender identity, as opposed to someone accidentally referring to a trans person by the wrong pronoun and the trans person going "haha got you now!!!". Intentionally or accidentally misrepresenting the law in this way seems to come across as just scaremongering.
If you can provide me evidence of this, I will be happy to concede.
"Social dysphoria can describe distress and discomfort that occurs as a result of how one is viewed by society. Assuming a person’s gender, using incorrect pronouns, or making assumptions about social roles in relation to gender can all be factors contributing to a person’s experience of social dysphoria."
https://www.goodtherapy.org/learn-about-therapy/issues/gender-dysphoriaAlthough there are bound to be many other sources for this, as constantly triggering someone's dysphoria by referring to them as a gender they don't identify as would seem pretty distressing.
