Neither. If someone is LGBT but agrees with the GOP on more issues they should vote GOP. Doesn't make them any better or worse than anyone else in my opinion. I think the LGBT vote will slowly drift towards being more even, although that may be stalled if more figures like Roy Moore gain power in the party.
The only way the LGBT vote will become more even, something I don't see ever happening, is if the GOP would stop electing homophobic assholes like Marsha Blackburn, Mike Pence, Kelli Ward or, like you said, Roy Moore. But under Trump, that wont happen.
