That depends on the bigot.

Some simply don’t want to associate with __________.
Some want __________ to live in separate places.
Some want __________ to learn to not be __________.
And many who may want __________ to die, don’t want to be the ones who actually do the killing themselves.

It’s only a quite small portion of bigots who have killed anyone. Bigotry is a much more common problem than murder.
