Not that I'm necessarily condoning what you may or may not have said. Without a log we only have your word to go on. And if Rampage wants to block you for whatever reason, well, it's his channel.
But I will say he definitely has insecurities. I remember one older interview, where one guy asked for his website's URL, and Rampage didn't know what that was. So the guy clarified and said link or web address. Then you could see Rampage was pissed, thinking the guy had made a fool of him by asking him something he didn't get. For anyone else, this wouldn't have amounted more than an "Oh, okay." But Rampage, he was smiling in that pissed off way, demanding why this guy didn't say 'link' in the first place.
Some might say he was just playing around, but I'd have to disagree. I get the feeling he was teased mercilessly as a kid, being called stupid and whatnot. He did say that he was nicknamed 'Rampage', because he could be driven to a frenzy as a child.
