In some instances, yes, some no. I remember around two years ago when I posted a picture of my Minecraft character on SG4 with full iron armour and captioned it "Hunger Games Pro" on Facebook. The very next day, some popular guy that just loves to tease, insult and just generally likes to make them feel like a piece of fecal matter called me out on the bus for it, and a few people were laughing and it was, luckily, never mentioned again. Everyone always thought it was a kids game that only nerds or people with no lives played, and how they reacted that day severely influenced my thoughts and decision pertaining to if I should continue playing or not.
I actually came up with a better solution; don't post pictures of it on my Facebook profile, and don't tell anyone I play it. That pretty much resolved everything, but I do think about that once every blue moon. Nowadays, I couldn't care less what people think of me if they know I play this game. I have a few friends that play it as well so it's fun when we get together on servers like Mineplex.
Moral of the day: Don't let stupid people stop you from doing what you love.
