It's not just homosexuality which the bible has issues with.
It also has laws against:
- who/what you can have sex with (there's quite a long list, including women who are on their period and the wives of neighbours [amongst others])
- what you can eat (you must not eat fat, certain animals [including rabbits, pigs, shellfish...])
- What you can say and do (you must not carelessly making oaths, lie, curse your mother or father, blaspheme...)
- How you look (you must keep your hair nice and tidy, not cut the sides of your hair, get tattoos, trim your beard, wear/produce clothing made out of multiple fabrics...)
- What and who you can touch (you must not touch certain insects or women [at certain times], amongst other things)
- Farming (you must not reap all of your crops [just the majority], pick up grapes which have fallen off the vines, cross-breed animals, plant multiple different crops within a single field...)
- Mistreating foreigners
- Working on the Sabbath
- Selling your land permanently...
I mean, it's quite a list to choose from.
Though, I can see why you singled out the easy pickings, as it is the one people tend to have the most issues with.
