ELI5: Why are rural and urban cultures so different?

One specific example: I recently asked my dad who lives in rural Australia if people in his community/town are homophobic, and he replied in a "D'uhh"-ish tone: "YES!!!"

Density and variety. You're squeezed into a much closer area, and a much more diverse one.

In terms of tolerance (sexually, racially, etc), one of the best ways to reduce intolerance is to expose people to different lifestyles.

In rural areas, it's not uncommon to have the same 100 or whatever neighbors for your entire life.You know them all by name, and they're all pretty much like you (immigration into rural areas is low). In the US, that usually means white and Christian.

This tends to lead to an "us vs them" mentality, especially when you add in things like news telling you about all the horrible things going on. Many rural people might never meet or meaningfully interact with someone who is gay/black/Muslim etc.

It's a lot harder to be afraid or hateful when your office mate who you BBQ with on the weekend is one of those things, and he's a decent guy.

In terms of other things, it often comes down to density. It's a lot easier to trust your neighbors when you know them all by name, and they've been babysitting your kids. In a city, you might buy a coffee, and never see that guy again. Even if say, 0.01% of the population are creepy, you probably pass by a few every day, just due to the sheer numbers.
