These days, I find it's just so easy for folks to hide behind the relative anonymity of the computer screen, and spend all their time taking gratuitous "shots" at others.

Maybe, because you spotted these things, and they never had, it makes them feel inadequate and threatened, somehow?

In any event, try not to take it too much to heart. An awful lot of people take their aggressions out online, these days. Many aren't as informed as they would like the world to think they are, also...and that is precisely the kind of person who reacts badly to being informed or corrected.

Understand that they have their reasons for being Stallone fans, and you have yours!

And, give them a wide berth...and do not look down on them, or at least, try not to. There are many things we all need help with.
