@astrobuzz I've lived in Lakewood/Golden for basically my whole life. While Lakewood and Golden can be somewhat conservative, I think that most of the people here are accepting, if not friendly, towards the LGBT community. If you're into riding bicycles, hiking, fishing, casual dining, etc., then I think Golden would be extremely welcoming to you.
On the other hand, Denver is far more progressive (relative to Golden, that is). I think it still has a ways to go before it's considered a true hub for the Western LGBT community, but it's on the right track. (For perspective: a gay friend of mine from Denver recently moved to Houston, which he raves has a vibrant LGBT community compared to Denver.) Anyways, if you're looking to have easy accessibility to the LGBT community, living in Denver may be better--but more way more expensive than in the suburbs around it.
I would recommend living in a city west of Denver, and spend your weekend time in Denver itself. That way you have a low cost of living, but you can have fun in Denver when you feel like you need it. Good luck with your decision!
