What happened to all are welcome coexist at comic cons?

The last few years at comic cons we saw all talking points like stand up for yourself, speak out, your voice matters and that??? Well it is all fake in my experience. I am a deaf disabled American creator I happen to be right they thrown me under the bush. They never stood up for me once when I was being targeted, bullied and ganged up on. They made up lies about me and others. They are the ones who said all are welcome and your voice matters. I called out cheating, sexism, choosing their friends and peers instead of others at comic gaming anime events. They falsely blackmailed and blacklisued me. That is illegal like the Hollywood blacklist. These events are so toxic to new comers, outsiders and new on the rise studios. They are hateful far left, radicals and gate gatekeepers and bullies.
