I think this entire argument is classic "logic overreach". This is all socially constructed. There is no perfect logical algorithm for deciding what is reasonable.

The rule is more like "don't randomly screw people". Ok, we've decided to screw this Nazi website. Hmm, is that a case of randomly screwing people? Nope. OK, move along.

> People can't discriminate on properties that the person they are doing business with can't pick or change [...] but can discriminate on properties that the person in question did choose or could change

Religious beliefs seem to fall squarely in the latter category (at least to the extent that political views do). Are you really comfortable with people discriminating on that basis?

In principle I'd be fine with including religion and every (political) view in that list as long as the view infringes on the freedom of the person doing business. For example: view (a) that demands that all living people must wear black gloves and run in circles five hours a day would be on my "that's ok to discriminate against" list while view (b) that requires the follower to wear a three-pointed pirate hat and eat pasta at its religious gatherings would not be.

Basically: If your view demands anything of me or any other person I might know other than pure tolerance of your view, I can choose to discriminate against you. If your view only demands tolerance and only makes prescriptions for you, I can't. Obviously, the real world is a bit more messy since even a political moderate view that demands higher taxes to feed the poor infringes on my freedom to earn money - so the question where to draw that line is a matter of open debate.

People who change their religion are often disowned by their family, their spouse might divorce them, etc. It can in no way be considered a choice.

I suppose you haven't heard of the "Trump voter divorce" yet, have you?

Political views are sometimes similar in character to religious views, such that expressing contrary opinions results in shunning and being ostracized by one's family and community.

It's one of the major reasons why free and fair elections have to use secret ballots, aside from vote-buying. Around here, it's risky to even participate in partisan primary elections, because employers can look up your name in the voting records and determine which party's ballot you used, then engage in party-based discrimination at work that ranges from subtle to blatantly overt.

While this area seems to have more than its fair share of petty and bigoted persons, it can basically happen anywhere that requires a declaration of party affiliation during the primary.

My own spouse has turned a bit more left over the years, even as my siblings-in-law have gone more to the right. It has resulted in some rancor, as those four gratuitously post replies on Facebook for each other's posts and summarily delete replies by my spouse. They're really being a bunch of a-holes.

If you don't conform to the views of your local community, you're going to have a hard time. And the more homogenous it is, the more you can be punished for your non-conformity.

It's still a choice to remain with your religion. It's not a simple one, granted, but if you stick with a religion that requires you to hate or be intolerant to other people, you don't deserve that others are tolerant of your religion. Hence they can choose not to engage with you. Why would hey have to bear the burden of you picking the easy path.

Lolwut are you serious?

You can't choose not to be gay, but you can choose not to hold hands with your boyfriend in public. Is it okay to discriminate based on that?

Does it harm you when others hold hand in public? No, it does not. It only requires a modicum of tolerance. So no, it's not ok to discriminate based on that. Or do you discriminate based on couples kissing in public?

I asked you to clarify your option four. Instead, you seem to have described a whole new option.
