Your logic is very faulty.
You are trying to say that because someone doesn’t, l’ma’aseh, do something, that it is proof that they know it is really wrong to do. You used “APY”s mashal about not eating sushi as a raiya.
Just because someone chooses for themself to not do something (like not eating sushi), does NOT mean it is inherently wrong to do, or that they believe that it is wrong for OTHER people TO do.
I’m sure there are things that YOU do not do. For example, maybe you do not play golf. Does that mean it is asur to play golf? Maybe you don’t travel to South America. Does that mean it is wrong for a Yid to travel to South America? Of course not.
THAT would make zero sense.
You and your chevra do not feel it is appropriate for you to wear jeans. That’s fine, just as it’s fine for you to choose to not play golf or travel to South America. You are entitled to your opinions, BUT that does NOT mean that any of those things are inherently wrong, or that doing them makes one less frum.
