"Homologism is rampant in my church. Everybody there assumes that you agree with waiting until marriage to have sex, even though most people won't actually care if you do it."
"I'm so tired of the way my roommate keeps homologising me. Yes, we are both gay, but that doesn't mean I agree with her that bisexual people are just afraid to come all the way out of the closet. Bisexuality is a real thing."
Noun - As in sexism or racism, binarism refers to a collection of harmful thoughts, actions, laws, and other social systems that uplift one group of people while erasing or otherwise harming a minority group. In the case of binarism, the word refers to actions and thoughts that promote the gender binary (male/female) while excluding, erasing, or otherwise harming people of other genders or no gender at all. People harmed by binarism are generally people within the nonbinary gender umbrella, or agender. Binarism is often exhibited towards nonbinary people by cis gender and binary trans gender people alike.
The adjective form of binarism is binarist. A specific thought/action/etc that exhibits binarism is said to be binarist in quality.
I wish people would say "honored guests" instead of "ladies and gentlemen" when addressing groups. "Ladies and gentlemen" is so binarist! It makes my heart hurt just to hear it. I really wish binarism wasn't a thing, and that people like me were recognized as being real.
It's like that term "wing man," except that it applies when there are more than just one person helping someone out in efforts to connect with someone they don't know in a romantic and/or sexual way. It's most often used in polyamory, when multiple partners support someone's efforts with a new partner. A wing team, however, does not always consist of established partners.
When Shelly and Anneli took me out to dinner for our triad anniversary, Anneli took a liking to someone sitting at the bar. Shelly and I had played wing team for Ann before, so we had the two them talking up a storm in no time at all, with full disclosure about our triad from the very beginning. Best anniversary ever.
