It isn't hateful, it's a parent demanding the respect they deserve.

Everyone knows that the beliebers aren't the bigger people, but Drake Bell is bringing himself to their level by being horrid and rude. It's immature. I don't really know who Drake Bell is, but I'm pretty sure he is supposedly "an adult" who need sot be called out on his childish behaviour.
Also you can definitely abuse your rights, including freedom of speech.

The problem with this is that the joke is worn out and he is just trying to piss people off at this point. Like, trying his absolute fucking hardest to piss people off just to get attention. Yes, beliebers are idiots, no you don't have to go insulting them every chance you get. What he's doing borders (well, he is kind of overstepping the border and that's why I'm commenting here) on things like bullying, harassment, etc.
Now, on the subject of first amendment rights, he is clearly abusing his. People say whatever they want waving the flag of free speech like "HAHA FREE SPEECH YOU CANT SHUT ME UP BECAUSE THATS ILLEGAL" and that is what leads some to believe that censorship is a good thing.

The last time I was on a plane I didn't have to put my drinking bottles in a plastic bag or my nasal spray.
And you need to put the tray table up because if you leave it down and the plane crashes the table could cut you in half.

God damn it, guest. I was gonna say that!
