This is all a slippery slope. When we start judging someone else’s actions we should also be judging our own.
I consider myself frum/yeshivish. But some would call me MO and others would call me Ultra Orthodox. It is a matter of perspective. At the end of the day we all need to follow a Rav and stick to that direction.
In my humble opinion, a lot of what I personally consider to be MO has a lower starting point then orthodox people do (I really hate labels). What I mean is, that in some situations the expectations are set lower so that being Jewish is appealing as compared to the the non Jewish world. This is because we are “enlightened” as a society. We need to get with the “times”.
And the opposite is true too. There are chumrahs invented everyday. If you want to be stricter on yourself that’s fine. But don’t force that on anyone else.
What I believe is most important, and it has already been said, is Achdus and everyone stop criticizing fellow Jews.
