They can be whoever they want. I don't think you understand my premise. People have a set of chromosomes. That's a reality. You can't change that. Sticking your fingers in your ears and screaming nah nah nah nah won't change that. They can have any identity they desire. What I'm saying is you can't control what I believe between my ears. I don't feel any hate toward them. But the simple reality is they were born with a penis or a vagina. Whether they cut it out and replaced it with something synthetic is another thing altogether. You can put a costume of a cat on a dog but it's still a dog. All I am is addressing is this simple fact, which many seem to be hell-bent on silencing. The silencing aspect is incredibly Insidious.
Typo: freedom of speech is explicitly, not implicitly, a constitutional right >

It is explicitly related to the government censoring speech, particularly political speech. It has no bearing on private restrictions of speech. 
I have no right to go into your church or business and start yelling about anything.   
The issue with social media is determining if they are the new ‘public square’ or news media or and advertising company or a private club… >

We need to foster a culture of greater free speech such that private organizations like social media platforms are not pressured to censor unpopular opinions. >

No, that tramples on the right to free association. If I run a website or business, I do not want to promote any speech from people espousing fascisty views.
We have a right not to associate with others based on their speech.
Free speech just means the government won't punish you directly. The rest of us are not required to listen or allow you to use our platforms to speak. >

I don’t want to trample your rights 🙄 
As I said I want to change the mind of people like you so we have a culture that does not try to stifle speech they disagree with. >

I don't believe that unlimited free speech overriding my will to associate with people whose views I find reprehensible is a virtue.
I don't think the government should jackboot into their homes, but they can GTFO out my business and my life. >

The two arguments can be opposite sides of the same coin, and free association is a tool that both can use to make their opinions known.
You have the right of free association. You have a belief that it's a good thing if certain people aren't given a platform. If you don't want to associate with certain people, you have the right to tell the platform that's how you feel, and to leave if they don't want to operate in a way you like.
Someone like u/terminator3456 has the right of free association. They have a belief that it's a good thing if all/some people are given a platform to speak. They have the right to tell any platform that's how they feel, and to patronize platforms that are more in-line with what they want.
You're both exerting social pressure according to what you believe. >

Free speech is disappearing. I stated my thoughts on transgender people, in that they are their original sex at birth with the added benefit of artificial hormones and some surgery. I mentioned I am fine with whatever they want to identify with. They are entitled to equal rights. I'll even call them ma'am or whatever they prefer. What I won't do is ignore common sense and the reality that a transgendered person born as a male is now magically a female. They're still a male filled with female hormones. 
For that, I was banned in two groups. Probably will be banned for writing this. It's pretty sad how people these days do not have the cognitive ability to hold two opposing thoughts in their brain. Freedom of speech is allowing freedom of speech. It's not hate speech when the science backs  me up. No one is "phobic," because they disagree, especially when science, reality, and common sense validate what I say. Banning someone for this is the opposite of free speech. >

The science doesn't back up your normative claim about the meaning of words like male and female. That is entirely outside the realm of the purpose of science. Nay what science does say is that supporting transgender people's identities improves their quality of life more than anything else.
Your desire to put people in little boxes has nothing to do with science.
