Meh. I think people forget that heterosexuality is not an aberration but an evolutionary norm and therefore deeply ingrained in every animal species including homo sapiens.
Homosexuality and bisexuality make up a very, very tiny percentage and that will never really change even when sexual fluidity is embraced. The percentages stay relatively stable across different cultures around the world.
There can be strong elements of biology denialism in feminism but all the feminist will in the world isn't going to change the fact that human beings have evolved to sexually reproduce and therefore heterosexual pairings will be the driving force in the overwhelming majority of people's lives.
Also worth remembering that the vast majority of women do not identify as feminists, even if they might agree with (radical) feminists on certain issues. Just like most people aren't Marxists even if they might agree on certain points about capitalism, workers' rights etc. If I understand it correctly, radical feminism is strongly grounded in Marxism? Therefore it's always going to be a very marginal and niche following.
It might be lovely to daydream about Wonder Woman-esque storylines of women only populations, but like many idealised notions, the separatist viewpoints tend to be devoid of realistic details in terms of bringing about this promised land / nirvana.
Focus on the topics that interest you and ignore the hetero-bashing.
The things that actually make a difference in women's lives are pragmatic ones that bring about change in the here and now, not utopian musings. If there were more pragmatic solutions, I think more women would embrace feminism.
