For a community that loves the constitution so much it's amazing to me how you guys love to ignore it when it isn't convenient for you.
Equal protection means that if a state has a set of laws (laws dealing with marriage licenses in this case) all people must be treated equally under those laws. Yes, that includes gay people.
Utter, self-serving fiction unsupported by history, intent or plain reading of the 14A.
There are no laws protecting polygamy in states, so trying to compare gay marriage to that is not accurate.
No but there is supposedly an amendment protecting freedom to practice religion as you see fit...except you can't. There are limits.
Ditto speech with its time, place and manner restrictions.
States can forbid felons from owning guns despite the supremacy of the RKBA.
Ditto states forbidding felons from voting despite constitutional supremacy AND the 14A.
To be president you must be at least age 35, a rather arbitrary number, despite the fact you have every other political right...unless you have not reached your state's age of majority.
Now, if specified rights can be limited why not a mere legal construct like marriage which the COTUS is silent about?
