How do you guys react to toxic fishkeepers

I'm sure you know the type. Most fishkeepers I've met online and in person are genial, polite, and helpful people, but there's a few exceptionally opinionated people I've ran into. There's the one extreme of doing things like chucking goldfish in bowls, and there's the other extreme of calling anyone who disagrees with them fish abusers. For example, I went down a rabbit hole on a certain tumblr blog I won't name, and it was basically them posting callouts about people in the hobby. Was viciously against divided betta tanks, sororities, and basically doing anything they didn't like. (I'm kinda neutral on sororities since I know many advanced fishkeepers have successfully maintained them)

Basically the whole blog was just extremely self-righteous and preachy sounding, and it seemed that anyone who ever so slightly disagreed with them was automatically a target, no matter how experienced they were. They seemed to act like they were some sort of ultimate authority on fishkeeping while backing up absolutely nothing they were saying. Anyway, I just mean to ask, how do you guys deal with those people? I mean, of course there's basic standards, but when you get into the nitty gritty of people attacking others for keeping fish ever so slightly differently it just gets really annoying. Thoughts?

 

I have seen people right here on this website argue that they have used what amounts to a perpetual motion machine ( a circulating siphon, in this case) as a pump.

Personal experience is one thing. Defying the laws of physics is quite another. I will always land on the side of chemistry, biology, and physics.

There's obvious exceptions to every rule lol.
