I would say that referring to gender critical feminists as "gender criticals" is quite dehumanising in itself, no?
The problem is that people like you twist language so much that we can't trust you when you accuse others of using, for example, "demonising and dehumanising language".
If you could actually give an example of a real quote by a real person, explain why you think they are a gender critical feminist, and explain why you think their language is transphobic/demonising/dehumanising then we could have a discussion about that.
But you won't, for obvious reasons.
Now, if I am to take you in good faith and assume that you intended your meaning to be clear, I would say the following.
If you were to say that [some] Mexicans are rapists, Arabs are terrorists, gay people are pedos [sic] or black people commit more crimes, you would quite rightly be accused of racism or homophobia. Even the fact that you have qualified your statement using the word "some" is no defence to this accusation, because adding the word "some" makes these phrases factually meaningless and so we have to ask ourselves why you are singling out these groups in particular.
However, if you say that "gender critical people are transphobic", even without the use of the word "some", this will be treated as a fact by many people who self ID as "progressive". Our whole group is regularly tarred with this accusation, without any kind of evidence or working being shown. Frequently we aren't even shown the courtesy of being labelled "gender critical" but are referred to as "anti-trans" instead.
So out of the five groups you posted, gender critical feminists are the only group about whom "progressives" consider it acceptable to make defamatory statements. Clearly you think it is acceptable, because you spend all day every day on here doing exactly that.
So are we to understand, from your inclusion of gender critical feminists in your poorly punctuated list, that you now agree that your defamatory statements about us are unacceptable? That they are, in fact, just as unacceptable as accusing Mexicans of being rapists and gay people of being "pedos"?
