I don't think that makes any sense, then; I mean, I don't talk about the "heterosexual lifestyle", which includes anything from swingers to singles bars to people who stay virgins until they get married and are faithful for life, not to mention polygamy, serial monogamy, adultery... It's not "a lifestyle".
A lifestyle should be a typical way of life, and the question of "which gender of people do you have sex with" is not a "way of life"; it's a tiny little aspect of a way of life.
The problem here is that there's a category error; since "practicing" homosexuals, as a group, are defined by their sexual practices, people seem to think this means that each individual gay man defines his life entirely around his sex life. This is no more true of gay men than straight men.
It's more useful to talk about things like "middle-class American lifestyle", or "Japanese salaryman lifestyle". At least those have implications beyond the question of who people have sex with.
I think you've misunderstood Romans; it's not restricted to hypocrites, but rather, to everyone who judges, because none of us can claim to be better than another sinner; our sins, too, offend God.
