If gender is fluid why can't sexuality be fluid...
Imagine if it were and what would happen if you spiked it with vodka...
Same thing that happens anytime a group of young free spirited people gets together. Alcohol is the great social lubricant, under it's influence people do ***they wanted to do but were too scared of social judgement to try.
Like killing people with your car?.
More like falling asleep at a really bad moment, or a dozen other dumb things that a person's rational judgement would recommend against. Alcohol suppresses that part of the brain that says "this might be a bad idea".
Humans suck, this includes you, accept that as an unchangeable fact of life and everything not only makes sense, but becomes much easier to deal with.
