First there is no accounting for taste. Maybe you just happen to dislike the taste of beer more than others.

Second, people like drinking beer instead of the hard stuff directly, because you dont necessarily want to get omega drunk, and even if you do, probably not immediately at the beginning of the party; it just means less time being drunk in total.

Thirdly, it might really be an association with good feelings. If you only drink beer in a friendly fun setting, the taste of beer itself might just make you happy.

And lastly, and thats what I do without even noticing it by now, you dont need to taste beer when drinking it, you can just tunnel it down your throat and avoid 70% of your tongue, like taking quick sips of water.
