For the most part, it's forgivable.
Just because you disagree with someone doesn't mean anything they do is worth nothing.
I mean hell, half this country likes Donald Trump.. What's up with that? Believe it or not, people you know, your friend's, family, most of the people at your church, probably support him.. That doesn't mean they don't have other decent qualities, right?
I often think of how many men of science.. The original gangsters of creating the world as we know it, were probably fervent assholes. At least a lot of them seemed to be. That doesn't mean they shouldn't be respected for what they did for science.
So unless the content of the creation reflects the views you disagree with, don't let it get to you.
Really. How many people can you even stand to be in the presence of for more than a few minutes. Most people are intolerable to each other. Surely they can be respected still in some ways.
