Not everyone is a boomer just because you cant handle alternative opinion. Half of you must be the offspring of boomers anyway.

Most of these soyboy Millennials were raised by single or divorced moms. Every masculine voice they hear sounds like their granddad, so they think all straight men are boomers.

Yes i think thats probably a good part of it. I wonder if it's those same ones with single Boomer parents that are predominately the ones saying it. Maybe they think they are being rebellious or something.

but it appears you have totally missed the point of the "ok boomer" meme's actual,underlying meaning.in fact,your meme is actually making the "ok boomers" point.

I wrote "When a stupid millennial" not "When stupid millenials" So probably not making their point. At least when your reading comprehension is fully used.
Obviously like any group, a stereotype is rarely actual and encompassing and I chose my language to reflect the point that not every millenial acts like this.
But if you choose to make stereotypes like the ones who say OK Boomer to everyone older than them, then they are stupid millenials and they should expect some return serve on it when they just blurt it out at anyone because they dont agree with them or they are older than them.
