It's not clear to me what you're referring to as "extremists" or by "transgender movement", because at this point that could mean a lot of things that almost don't even exist or it could just mean "anything I don't like".

But even if it did refer to actually existing extremism, presuming a trans person should know about a sub-category of extremists that happen to be trans and make unprompted verbal attacks against them just to signal some kind of virtue at is a pretty weird demand of compelled speech on your part.

This kind of shameless bigotry and stereotyping is pretty transparent.
