If Trump is innocent of collusion then WHY is he acting so guilty?

im not one for all this political nonsense. but i was bullied. both growing up and online. at some point when you have a group of people who constantly attack you as a lot of people do in real life and on these social forums you tend to fight back. just because a person fights back doesnt mean a person is guilty just means that person is tired of all of it. i would think if there was something that should have been proven it would have been. its been like what just about a year into this investigation and nothing has popped up so far. what ever happened to innocent until proven guilty. i dont like the guy. i think he is scum for many reasons but im totally hating this hate culture that has been going on. people making things up for their agenda and because their party isnt in power. both sides do this kind of thing. obama wasnt a US born citizen or that he was a musilim. both sides make up things to attack the other and they get so worked up and spouting hate. its just dumb.
