It also happened to me 3 yrs ago but in a different situation. I happened to make some remarks that the guy misunderstood as prejudicial on him so he blatantly told me good bye and said I am not the kind of woman he was looking for. I sent him a "sorry" card and remained silent. After a few months he messaged me that he is still interested to know me and hope i do the same. i accepted him again and again apologized and he said there's no need for an apology. Our friendship was rekindled again but I'm more careful with my comments now.
I do understand that this is an international dating site and everybody's welcome from all parts of the globe as long as you follow the rules set by the site administrators. But you have to consider that coming from different countries or regions or whatever, we have also different traditions, culture, values and upbringing. So don't impose your rules since we may be following another rule. As long as we don't offend anybody, extend proper courtesy, no offensive language or porno pics we are within the parameters of the rules and regulations set forth in the site.
I never imagined being silent as rudeness to others. What I know is that if you have nothing good to say then it is better to shut your mouth. Even a fish can get out of trouble if it shut its mouth!
I am locking this topic as it turned into a fight, it's no longer an opinion exchange. No need to escalate it any further.
