We need them now more than ever since religious/political/racial motivated assaults are way up. Going out to lure a (insert appropriate racial/gender/religous group) person into a beatdown or vandalizing a place of worship or political office are not simple everyday crimes and have the potential to spark civil strife or revenge crimes so they deserve harsher sentences. No one objects to any of the other kinds of laws that lengthen sentences for various circumstances surrounding the crime so why just this?
That's an absurd position to hold all the way around. For starters, we already have laws to prevent those crimes. If those existing laws won't prevent the crimes, this certainly won't either.
Second, and much more importantly again, there is absolutely no way for the state to know what the person was thinking when they committed that crime. It's beyond irrational and unconstitutional.
