>>How come these things are conveniently forgotten by people saying that the bible says that 'homosexuality is wrong'?
There are 2 answers.
1)Those were specific laws to the Jews, which were outmoded under the new covenant thanks to Jesus... Levitical laws in particular are normally considered to fall into this category
2)It is correct that the bible does not say one type of sin is worse than another, so in away you're right... gay sex is not worse than thieving or adultery or lustful thoughts.
You should note though that the claim shouldn't be "homosexuality is wrong", but "acting on homosexuality is wrong"... in the same way that sex with someone you're not married to is not right, but sex itself is not bad or wrong in any way.
