How do you deal with a friend that likes to argue?

I have a friend that likes to argue about anything and everything. If there is something controversial going on, she’s posting about it. She likes to argue about topics where there are often pro’s and con’s, but she often picks her side and doesn’t listen to anyone else’s.

Recently, she made a post about a controversial topic. It is something that parents face, but she isn’t a parent. She chose her side and basically said anyone against her side is evil. Well, I am not against her side but I did the thing she was referring too (I won’t say here because I don’t want a debate). She probably doesn’t realize I did the thing she states as “evil”, but I thought it was an ignorant comment.

Anyway, as an adult, how do you deal with a friend who is constantly battling everything and everyone? I ignore it, but I’m always afraid she will flat out ask me my stance on something and if it’s opposite of hers, she will battle me. I always see both sides to a situation, so I prefer not to argue.
