If you are implying that in the recent era - we'll look at 2013 leading up to same-sex marriage being legalized - that there was rampant homophobia, the data does not support your claim.
According to the FBI, in 2013 there was 334 hate crimes committed against LGBTQIA+ people [1]. The US population back then was 315 million [2]. In 2013, according to Gallup, 3.6% of Americans identified as LGBTQIA+ in 2013 [3]. Which means the crime rate was 1 per 33,952 persons, or normalizing to per 100,000 as crime is usually reported is 2.94 per 100,000 which is on par or LOWER than any other category of heinous crime for that era. In fact, 2013 has one of the safest years on record [4].
Furthermore, public sentiment had already switched in favor of same-sex marriage before it was even legalized, according to Pew research [5].
