Although there is always room for improvement, Sweden is very progressive compared to other countries. You can read more here:https://en.wikipedia.org/wiki/LGBT_rights_in_Sweden.
You're probably thinking of tycker om. It's important to realise that tycker om is not a verb + a preposition, but rather a verb that consists of two separate words, and if you leave out either word it completely loses its meaning.
Hence, the om doesn't transfer, since it's part of the verb. Swedish has many verbs like this, where the verb is composed of multiple words - but älskar is not one of them.
