What type of fallacy is this?
Reporting on the health risks of abortion has become taboo in the United States because special interests do not want abortion banned.

Because you are saying something that is not politically corrrect.
You can not speak out about anything moral, anything against any minority right orr life styles that are not tradditional.

Better to ask this question on the Philosophy board.

I think it is an informal fallacy . The idea that "discussing the health risks of abortion is taboo" is a false premise. But if it were true then all you could conclude is some special interests do not want abortion banned while other special interests groups do.
