There are plenty of little control freaks running about, desperately trying to be the big bad bully, and you will be running into them where ever you go. Learn to deal with it. Reddit, Facebook & Twitter are magnets for these creatures. The silly r/linuxmasterrace is not the only game in town. Find a better place.
If you get to my age you will understand that the opinions of others are meaningless, as is what is cool or not cool. No one can peer-pressure you into anything unless you let them, and no one can bully you unless you let them. It always takes at least two to tango. Now is the time to learn self-confidence and those skills necessary so you can eventually stand up for yourself. You need to decide whether you will go through life on your own terms, or as the doormat of others.
