Frankenstein monster is kinda like Trans folks or people

For me that red line will always be cruel bigotry, even if it does incur the disdain of the self appointed intellectual conscience of the forum. Can you see Texas from that high horse?

I'm on the other side of the world from Texas.

It was obviously meant metaphorically, not literally. 

Some people are stricter than we are concerning their epistemology. They think that we should only believe in those things for which there is objective evidence, and that subjective testimony is not good enough to be persuasive. 

Since I made no claims about the truth of anything, one wonders where you think this none too subtle straw man is going? I made a moral judgment about a post, and morality is ultimately subjective. Since all moral claims ultimately rest on subjective opinion,  not objective truth, though I am happy to listen to any arguments against this notion. 

Nor did I endorse any purely subjective testimony. Strike two...

So they don't accept the subjective testimony of people who say that their gender is different from what (until recently) was taken to be objectively indicative of maleness or femaleness. 

Again I endorsed no such claims as true or false, and I don't care that the subjective morals of others are content to indulge bigotry and prejudice, I hold a different, though equally subjective, moral view. 

Objective evidence would include things like chromosomes or anatomy, or other observable, empirical evidence. For our more accepting attitude, subjective testimony is sufficient.

Then they're using a false equivalence fallacy, that wrongly equates gender as being the same as biological sex. they ought really to grasp basic understanding of the topic before commenting, and none of this changes the fact that the OP was trolling, and showed zero interest in honestly debating the topic.
