You don't have to justify your actions to anyone. Nor should you feel compelled to do so.
Just like your ability to respond to someone, ignore them, start your own conversation, etc., you are not beholden to anyone or anything except the basic rules of the Forum.
Strangely, what just happened which prompted my response is emblematic of the problems I tried to explain to you in my earlier post. This idea that one must always adhere to dogmatic views, must comply with limits on who you talk to and what you can say, or how you choose to peacefully express thanks, appreciation, or other consideration on pain of being "outcast" is the problem.
So I say "LIKE" whom you wish, dispute or agree with people on a case by case basis as YOU so choose, and do not fear peer pressure. This is an anonymous Forum, and you just be you!
Captain, I salute you. That's a very nice post, I see your point, and I sincerely thank you!
