Why though?If I can't decide why I hire or reject an applicant then suddenly that applicant has more rights than me in this situation even though it is my business. That seems kinda off.

That isn't really correct though. If not wearing an attire that is appropriate for that business is part of my personality then I'm getting rejected because of that. I can't change mypersonality. So forcing a shirt on me and act like a normal person is the exact very same as forcing a gay person to act straight.

Both don't hurt the person physically and both are easily possible but both will make that person feel really uncomfortable and wrong.

What if their gender or sexuality would disrupt my business in some way? Be it that they can't work together with my extremely religious employees or because my horny employees get distracted by that sexy new employee. They're all good and productive employees but they have their faults like everyone else. Should I fire them instead just to conform to social demands?

So I should discriminate against all my workers who have always been loyal and efficient workers in the right conditions so I can just higher one additional person?

Yes, that is weird and against any business sense. Why even make a private business if I have to let society dictate how it operates even though it does not hurt anyone.

I hate wearing suits. I can't even wear them because I easily sweat in them. Making me wear one is extremely uncomfortable for me. This is not a mental disorder but just personal preference. I don't see why my "little inconvenience" is less valid than someone elses.

You're not really likening putting a shirt on to changing your sexuality, could you start being attracted to men if you were asked to?

And what if I opened a business and told black people, jews and asians to stay away from it? You have the right to be a bigot and have a closed mind but not to discriminate as far as I'm concerned.

You mean it hurts the one job applicant I didn't take? If that constitutes as hurting someone then no business ever should be allowed to deny any applicant because of any reason.

Again, you're drawing arbitrary lines and put seperate worth on people's life choices and personalities.

You're saying someone who disrupts business because of incompetence is less worth than someone who disrupts business because of their gender. Well I have news for you, intelligence isn't a choice. Why are we allowed to discriminate against stupid people but not gender?

Read again. I said "pretending to  straight". And with that I don't mean sleep with the next person of the opposite sex you see. Just not give any clues as to what sexuality you prescribe to. Which should be possible for any gay person. Like it is possible for me to pretend I'm a civilized person even though I'm really not.

That bolded statement contradicts itself.

I'm honestly not sure where the idea what business owners should be free to do whatever they want because they have a privately owned business came from. You can't legally sell whatever you want, and you can't legally sell certain things to certain age groups. I don't see many people pushing to make it legal to serve alcohol or sell firearms to children.

If you open a business available to the public and use city and state resources such as roads and venues, you must serve the whole public and follow laws, and you pledge to do so whenever you apply for a business license. If you don't want to do business with a certain group of people, then you shouldn't open a business. That's your freedom; the freedom to operate a business that abides by the law, or to not operate a business at all.

I prefer to live in a society where freedom does not mean legally enabling bigotry in business practices. So I'm glad I live in a society where that is not allowed under the law.

Individual people are free to be bigotted arseholes in their own private lives, but when it comes to the work place and business environment that shit needs to be left at the door, and if you can't leave that shit at the door the law should make you leave that shit at the door.
