Like, for the love of God, imagine if it was the other way around and I was the one saying YOU were underage for posting something like this. Wouldn't really give me a good look, right? I'm guessing it would hurt your feelings since it is harassment. You definitely would not be happy with someone calling you underage online even though you are clearly an adult?

Then why the fuck are YOU doing that shit? You wouldn't like it if you were the one in this position, so why are you doing this? It's not a good look for you. You can't just assume someone's age! If you do it makes you look like an asshole.

I'm not saying it to be mean, I am saying it because that is how it is. Treat others with the same level of respect as you want and people would share the same amount of respect back. Just appreciate the meme and move on, or don't, continue to act the way you are acting right now, and lose the respect of everyone around you.

You have to give respect to earn it. You didn't, so that's on you.
