Is it really that far fetched to think that if someone had been harassed and bullied most of their life by a certain type of person (tall/muscular/imposing/etc) for being gay they'd be more inclined to shut them down immediately, and just outright not want anything to do with them?
Yes.
Is it kinda prejudice/judgemental? Sure. But in Liams mind he's just stonewalling to save himself from the likely harassment for being gay yet again.
"My brothers were big and teased me for being X. I'm going to not trust anyone who's big!"
Seriously. That's the reasoning. Every gym goer, every body builder, every guy or girl with some musculature is potentially going to treat me poorly? Bullying?
Sure, a traumatized person of anything would have
some trepidation. But the MC is talking to Liam in the simplest, most unprovocative way. If the topic was sexuality, that
could be different. Did Liam not talk to
anyone else who flexed a
bloody muscle before? Didn't Liam mention gay men are even dirtier in their conversation? What's the issue?
But even if the topic was sexuality, adults, and people learning to become lawyers, would not even come close to this reaction. Especially considering how friendly the MC and his group are. This is some childish stupidity and makes little sense.
And people with family quickly grow up and learn that brothers and sisters are different from others, regardless of how they teased each other growing up. Combine that with: 1) being adult, where Liam must have interacted with hundreds of people by now of different shapes and sizes on much more mature topics, 2) being in an academic setting where such bullying behaviour would get you expelled, 3) the MC acting and sounding totally normal to him and others that he can observe publicly. It doesn't make
any sense!
And Liam is gay. So, wouldn't he be attracted to a nice, muscular man around his age, being cordial and friendly for a change? In public? Is Liam so biased toward appearances, he can't understand human behaviour? Athleticism bad? (Is our MC one big giant jock only into heterosexual sex, who
hates the gays?) While studying to be a lawyer, who needs to learn to read people, and understand laws, how they're applied, and communication?
And, come to the live conclusion that there are many people in the world who look and act differently? The way anyone else would, regardless of all this discipline and knowledge in law? What motivation would someone ever want to bully Liam in this scenario?
No! No, I'd say this is
pure stupidity. Either characterization or character. Fine for a character flaw, I
suppose. But sounds like it'll just be some obstinate bias that amounts to not much.
