I’m literally the most left person I personally know by a wide margin

So you don't count people you know online, you also don't go to organizing union meetings, are not part of collectives and not part of a real left party (thus are likely an individualist, moralist, idealist liberal who will often - since there is little self critique and reflection - for example having thought how you could integrate parts of being anti racist in your life within a group). Of course you might be called a reactionary in some cases. Feel free to link to them, post those opinions in the un-safe space we got here as quote and people can do reflect on that. Taking your quote (which likely ignores context to present yourself in a better light) I have to say that:

trans people should be able to do whatever the fuck they want" (good) "***********************” (bad)

Yeah that is reactionary. You were rightfully banned as you broke server rules. There were enough campaigns i.e. "Read Trans Liberation!" for you to educate yourself. You didn't. You are not the victim here.

To break it down: You went into a space of solidarity and then climbed on a chair and yelled "I don't care about [group you are supposed to be having a minimum degree of solidarity with]". Everyone is able to understand that this is even if it is your uncle's birth date and you would yell that you don't care about your uncle it is a social faux pas. However what you did is much worse.

The website's slogan at that point even was "We love our trans comrades!"

Besides:

and told to k**l m***lf and then a mod agreed with them

X: [Doubt]

You already showed yourself to be an unreliable narrator, no reason to believe such an extraordinary claim.

Edit Wonder who downvotes this post

Edit2:

CW in effect transphobia commited in a save space, with multiple repeating posts and comments and an unwillingness to see the perspectives of others, this is the context of what OP did post:

I heard things similar to that within the spoiler during the 80s when I did attend gay meetups, protests and LGBTQ* representation in media became slightly more common (while what we did was still criminal in many places). Turns out I wasn't gay btw. I was bi (and that includes trans people as bi is defined as having attraction to more than one owns gender) and still am, but was, too. However the gay spaces were the spaces which enabled me to be myself and not the eternal cycle of "this is too much progress for the [women/black people/jews/italians/gays/insert minority/marginalized group of your choice]! they would progress more if they would be silent and try to pass as cis white evangelical hetero who eat meat and drink beer in unhappy marriages!"

fawx has the capacity to change and act different, as well as to not slander thousands of users with re-tellings of stuff that didn't happen like that and which minimizes their actions (which is understandable human, but it remains wrong. I do understand the emotional feeling of giving somebody a wipe as fawx did try to do with depicting hexbear as bad for excluding him for no reason - and the willing audience of people taking that for a fact instead of doing their due dilligence). Still the burden is on fawx to read, speak, listen and not primarily center themselves. If they are actually in the union they have enough ways to grow (attending IWW and other fighting unions organizing meetups and summer schools for example).
