I would say that while the situation was unfortunate, and probably left some bad feelings, you were within your rights to express your opinion, and since there’s no law requiring you to patronize his business, you can take your business elsewhere with a clear conscience.
I might not have done exactly what you did in the store, but I likely would have not gone back to the store either. I prefer to patronize businesses that share my beliefs, where possible.
With that, I must sign off, as it is way past my bedtime. G’night and God bless.
Thank you for the courteous response. I'm also heading off for some overdue snoozing and I wish you God's Abundant Blessings as well.
