If you own a business which employs homosexuals, you can bet your bank account that they will.
I owned a business that employed a total of three homosexuals that I knew of:
One I fired for wasting work time on non-work activities, copying fliers for a gross "party" on my copier and taking several hours to do it when his group was facing a deadline, although I waited two weeks and told him I was cutting back in his area of expertise.
One moved on after a year - she was just working for me to get the training in professional statistical work.
One I set up in business on his own when I shut down my business - he was a good, decent, honest worker who kept his personal and professional lives completely separate.
If any had demanded special accommodations, I would have given in immediately to avoid lawsuits, and then fired them a few weeks or perhaps months later for unrelated reasons.
