Yes, if it's not illegal, then it's OK to do. You're arguing with yourself, I hope you realize.
Not necessarily okay, but not illegal. I hope you realize simply saying something is okay to do suggests moral and ethical attributes in addition to legalities. Because something is legal to do does not make it okay morally or ethically. It only makes it legal.
I've never said I would answer it nor am I obligated in any sense to answer it. It just so happens that the question doesn't make sense concurrent with my complete lack of obligation.
No one here has an obligation to answer anyone here. We're here voluntarily because we want to engage subjects, and hopefully with others who are honest enough to answer questions asked of them as they would have others answer their questions. When engaged in discussion common courtesy is to answer relevant questions, and in this case you've repeatedly refused to answer a quite simple question, a question that would test the edges of whatever position you hold in relation to discrimination we find in society. At this point my thought is that you don't want to share whatever is your real position in relation to societal discrimination. But my question remains should you want to pursue the subject of discrimination we find in society around us.
Are there any questions you've asked of me that I've failed to answer? If so please let me know.
