Sorry for the rant here, but this NEEDS to be said:
If you post stuff from Tumblr, weheartit, Pintrest, iFunny, or whatever the hell it is, THAT IS OKAY.
If you do not post stuff from other sites, and make your own quotes, THAT IS OKAY.
Bashing people over posting stuff from other sites IS NOT OKAY.
Steve has even said that it's okay to post stuff from other sites.
If you don't like someones quote, you don't need to comment on it.
Also, one last thing: if someone has an opinion that's different from yours, THEY ARE NOT SHOVING THEIR BELIEFS DOWN YOUR THROAT. They ARE stating their own opinion and that is perfectly fine.
