It is. You are assuming the two sides are equal. They aren't. One has had almost all the power since January of 2017. The other hasn't. One party is supporting an odious President whom they see as a means to an end for their political agenda. The other isn't.
Attempting to put forth an objective case for why the other guys are worse when you're obviously partisan yourself is a sham.
Translation: The tolerance level isn't the same because the other side is evil (ie: I disagree with them). Therefore, our over-the-top actions are justified. The antics of the left have NEVER been duplicated by conservatives. When we lose an election, we go home and eat dinner with our family. Life moves on. Not so much with liberals.
