Unfortunately, you're several years out of date.
Here's my best compilation of how states got gay marriage into place. Please note this may not be entirely accurate, and in some states the record is more complicated than indicated here.
Legislative action (11): IL, HI, NJ, MN, DE, RI, NY, DC, NH, VT, CT
Referendum (3): MD, ME, WA
Court decision (federal or state) (15): NC, WV, NV, CO, IN, WI, VA, OK, UT, PA, OR, NM, IA, CA, MA
The political process, by referendum or statute, is thus very nearly tied with the courts in putting this into place.
Conservatives do themselves no favors by refusing to recognize that there has been an amazing shift in the public opinion on this issue.
When you lose a battle, the best thing is to fall back, regroup, figure out why you lost and how to win next time, then go back and fight some more. Refusing to recognize when the battle is lost only results in unnecessary losses with no chance of victory.
“Conservatives do themselves no favors by refusing to recognize that there has been an amazing shift in the public opinion on this issue.”
I think conservatives also do themselves no favors when they whistle past the graveyard with statistics about homosexuals being only 2% of the population.
The percentage may be correct but a lot more than 2% support same sex marriage.
Another faulty stat, IMHO, is the percentage of Christians.
I think a lot of people claim to be Christian but it’s lip service only.
Your battle analogy is fine when body counts are in play, but we are now dealing with minds. This is far more difficult to regroup and retake when the mind is brainwashed, trained to get things for free, ignore responsibility, do it if it feels good, count on government, etc.
