Number 1 - Your first paragraph and statement is exactly what the problem is, on both sides. While you may choose religion as your "do not tread on me" issue, many also don't want to be told to accept that a man who now identifies as a woman should be entitled to participate in womens sports. Is this really a lack of inclusive thought? While I am not an overly religious person, I could argue your stance is no different than mine. Maybe some of those who can't quite crack the Hawks line-up should give it a try?
Number 2 - The debate regarding gay marriage had far more to do with the legal components such as a spouse qualifying for health/life insurance, medicare, child visitation, etc. Not the issue of sexual peference. Different topic. Yes, extreme religious groups have do have an issue with the sexual part - and far right white Christians aren't the only ones who do. Though that group is the one that gets the heat for it.
Number 3 - I am glad that we agree and thus should address 2016 and what was done there.
