False equivalence in scientific opinion isn't any different from the political sphere, its just that many political issues are actually more highly debated because of a lack of hard science behind them.
Further, still a flawed argument; part of the main point of science is to consider questions that may be emotionally loaded or painful in a scientific manner. Forbidding certain streams of thought because it could conceivably be used to support a politically unpopular position is unscientific. At the very least you ought to acknowledge that is the case, rather than try to pretend that you have not somehow left science behind, and pretend that you will suffer no consequences from that because of the sheer, self-evident rightness of your beliefs. (And if those last six words don't at least make you pause, you don't have a scientific mind.)
