Homosexuality Will Always Be in the Minority
Think about it.
Unless there’s an explosion of gay couples adopting children given up by straight women/couples on a HUGELY disproportionate basis, gay people just won’t be parents on a large scale.
Therefore, fewer people will be exposed to the gay lifestyle as something they grew up with.
Therefore, fewer people will see homosexuality as the norm (it is already this way. Right or wrong, it’s just not the majority of people).
Straight people will reproduce, and by and large, their offspring will grow up, partner up heterosexually, and have babies, furthering the heterosexual norm.
