"Jesus would rather kill, not marry, gay people" - Franklin Graham

[SteveII]

So, does "not compelling objections" mean the beliefs are baseless? unreasoned? homophobic? bigoted? No. That's what your side of this issue does: mischaracterize and then bash the straw man with over-the-top labels. They somehow feel that if they understand the other side's position, then they have to admit something that they don't want to admit--namely that Christians beliefs are not inherently baseless, unreasonable, homophobic or bigoted. 

Also, the opinion of Christians =/= Christian beliefs derived from systematic theology and the development of sound doctrine.

Yes, actually, it does mean that it is unreasoned and bigoted. If your religion says that it is wrong for two men to love each other and be sexual or two women to love each other and be sexual, then it is your religion that is wrong. it really is that simple.

First, no, it is reasoned: 

1. Marriage was ordained between a man and a woman from the beginning--with no ambiguity.
2. Sexual immorality is sex outside of marriage.
3. Sexual immorality is a sin.
4. Homosexual activity is outside of marriage (from 1)
5. Homosexual activity is a sin (from 2 and 3).

Second, beliefs cannot be bigoted, only people. 

big·ot·ed
ˈbiɡədəd/
adjective

1. having or revealing an obstinate belief in the superiority of one's own opinions and a prejudiced intolerance of the opinions of others.
   

I am not intolerant to the opinions of others. I understand your opinion and respect those that hold it. It does not follow that I have to agree with your opinion or I am a bigot (which is what you need to be true for your charge above to be true).
