The meaning of the word is not restricted to just a specific generation, and calling someone a boomer is not always an attack that requires a fainting couch. People can call themselves boomers if they are having trouble setting up something on a computer, etc.
Lol. I can assure you that my response to someone telling me “OK Boomer” would not involve an attack of the vapours and fanning myself with a handkerchief. But, the response it warrants wouldn’t really fly by forum rules, so I can only attempt to explain the case for objection. With regard to what people call themselves, I'd say there is a pretty major difference between someone saying, "Oh, I'm a silly old fool," and someone else dismissing them on the same basis.
"By that logic, the term "faggot" is fine." Depending on the context, yes.
Well, the context in question is this forum. I’m assuming that’s not acceptable here? But I think you’ve again missed the point. I make the comparison, because you suggested that the term “OK Boomer” is often not directed at someone actually of that generation. But, if you think about it for two seconds, even if you address the term to someone who is not a Boomer, or not gay, it only makes sense because of the negative stereotype implied, which remains pretty obnoxious.
I don't mind letting this strand of the thread go, but I will answer you if you carry on rationalising and attempting to dismiss the argument by portraying those irritated by such an attitude as less than charitable and in need of a “fainting couch”. I see why you might sympathise with the poster, coming from a similar school of argumentation.
