Fish is not categorized as "meet" not even "meat". But as others said: People love getting told what to eat, do, drive, think, vote.

What kind of definition or distinction do you apply for deciding what is meat?

Because I personally struggle to find a reason for why fish should be an exception, and at least Wikipedia also defines meat as "animal flesh that is eaten as food".

Many cultures draw a clear dietary distinction between between meat, bird, and fish (With 'meat' specifically referring to mammal flesh).
