Yeah. Because it IS A FUCKING HATE CRIME, no matter who does it!
If a group of homosexuals did the same thing, they would be arrested for hate crimes.
If a group of atheists did the same thing, they would be arrested for hate crimes.
If a group of animal-rights activists did the same thing, they would be arrested for hate crimes.
If a group of homeschooling activists did the same thing, they would be arrested for hate crimes.
If a group of Democrats did the same thing, they would be arrested for hate crimes.
If a group of Republicans did the same thing, they would be arrested for hate crimes.
Attacking people based on race, creed, religion, orientation, gender, etc. is a hate crime, no matter who does it. If it had been anyone else doing this, they would have gotten arrested too.
