Unfortunately you're buying into a lot of propaganda that persists to this day.
Straight sex workers exist. Given straight people outnumber gay people by (let's say) 10:1, there is almost certainly a higher absolute number of straight promiscuous potential superspreaders than there are gay ones.
Even in the middle of the bell curve, nearly 50% of American babies are born to unmarried parents, so it's not like strict monogamy is the norm among straight people [0]
The reason that HIV transmitted so well in gay male populations is because receptive anal sex has a 20x higher likelihood of transmission than receptive vaginal sex and a 40x higher likelihood of transmission vs. insertive sex.[1]
Within the gay community, you have plenty of men who engage in that relatively high risk act of receptive anal sex, who then go on to be the insertive party in another interaction.
Within straight populations, the potential spreaders are just much less likely to contract HIV in the first place.
Sorry to be so specific about something sexual, but I have always found it odd that this very practical information has not been put into the mainstream. I guess it's the imperfect middleground - people who want to shame gay men don't care about the data and people who support gay men don't want to stigmatize receptive anal sex. But unfortunately, I bet it's led to a lot of needlessly risky behaviors.
