Perhaps but I think it's just a normal ick response. People instinctively steer clear of "weird" or "perceived to be dirty" things even if it's illogical. (No matter how much some try to gaslight, homosexuality is abnormal. Note that abnormal != wrong. The former is a factual statement and the latter is a subjective/moral one, though for better or worse most of the globe does still treat it negatively and it's only in the social bubbles that we're in where it's accepted)
