How is this any different from the people who wanted to cure homosexuality in the 90s and 2000s?
It is quite similar.
The people who wanted to "cure homosexuality" did not have good intentions either.
But it's still in a different category than wanting to murder a group of people.
Sure, but murdering people is what this CPAC person is calling for.
The CPAC guy knows what he's doing, and baited a particular reaction.
Social conservatives will tend to think trans people are wrong, and people who follow the issue should recognize that this is a big part of the argument. A call to eradicate transgenderism is for many on the right the equivalent of a call to eradicate anorexia. It doesn't mean they want anorexics to die, and any such claim should be recognized as being highly misleading. It's not as if CPAC speakers secretly believe that millions of people would be better off with hormone therapy and sex change operations, even if you believe that would make their quality of life better and lower the rates of suicide.
