And conservatives sue or try to sue?

The liberals that get vocal are usually very young with very little experience in life. You can't take them seriously most of the time. When they started acting up in the streets in California when Trump was campaigning for the primaries they showed the protestors. The photos were a bunch of young punks. They weren't making as much of a political statement as they were just doing what bored kids do.

Look at the photos of Occupy Wall Street. It's a crowd of all ages.
