Yes I have, usually in regards to the silly things discussed in this post IE Do wearing jeans make you less religious or is it OK to have a day job etc…you get the point
And do you point out how wrong it is for those people to group other Jews into categories of thought based on the way they dress (e.g., the black hats), as you have in this forum when it’s the pants being discussed and not the headwear?
I personally find the blue jeans -> MO assumption way less offensive than the black hat -> silly assumption, because calling someone MO is not an insult.
