Anti government intrusion.
"We're not pro-murder, we're pro-choice."
"We're not pro-abortion, we're pro-choice."
"We're not pro-sodomy, we're pro-choice."

The question isn't whether it is moral to criminalize intrinsically evil acts, the question is whether it is prudent to criminalize particular evil acts.
I see no prudential reason to decriminalize sodomy. Those caught in the act should be prosecuted. However, that does not mean that the police should put cameras in bedrooms.
