Until we can truly pay attention to healing ourselves, the division, shame and resultant guilt will grow. Our children will grow even further away form what it means to be human, have a horrible time making decisions, choosing careers or finding a mate. Fear and guilt paralyze. You can't cover it up or hide it away behind religion, alcohol or porn, or whatever your chosen methods of self- destruction. Until you deal with your own shame and hurts, you will pass them along to your children, tenfold.
You don't get to hide behind your religion and judge others for what your perceive their walk with God to be. That is between them and God. Hate has nothing to do with God. You think that you are hiding within your holier-than-thou attitude, but you really just look cruel and close-minded. And you aren't fooling anybody but yourself. There is no room in this world for bigotry, misogyny, judging of folks for their sexuality, or hate of any kind. When you judge others, you don't just hate- you ARE hate.
As owners of human bodies, we don't really get to decide to not care about our health. The consequences of this decision are a lifetime of constant struggle, descent into multiple diseases, a broken gut (and therefore broken brain) depression, and potentially, so many prescriptions that your head will spin.
HONESTLY, I hope your family understands healthy separation and the meaning of LOVE. Because it is a whole ton easier when this is not a hurdle that needs to be climbed, jumped, burned, argued over repeatedly, revisited constantly, and then, hopefully, eventually, sunk with an anchor in the farthest depths of the darkest oceans.
