Out of the loop

Well, they can ask anything they want, that's fine.

But why should anyone waste their time searching for some random term?

Any given post that's asking a question is a request for a person to spend their time doing something for the poster. There are some people willing to go the extra mile and look up things they have no interest in at all. There's others that won't go that far, but would look into the subject with a little groundwork already done.

In this case OP is asking about not the person themselves, but the response to that person. There's no mention of where those responses are, and no information to help with that.

Now, there may still be people willing to look up the person, then track down whatever it is OP is talking about regarding that person catching heat, then come back and cobble together an answer. But there's less of those than there are that would follow links and then expand a search.

I'm not asking for more information for myself to do this. IDGAF. I'm trying to guide OP to getting the answer they want, faster.

It isn't about a magic threshold to ask. It's about helping the crowd come up with a useful answer.

On a personal level, why the fuck would I want to search for some random person by user name? Anybody out there that's publicly known by a user name instead of an actual name isn't worth the time of looking up, which is extra true if the platform the user name is on isn't known. Again, that's for me personally; anyone else is perfectly free to do whatever they like.

Yeah, anti-zionists are pretty infamous for hating trans people.
