Charles, I have known you to be one of the most thoughtful and courteous posters on FR. I have not always agreed with you, but you have always treated me and others with respect AFAIK.
But, I do butt into conversations when I find them interesting. After all, that seems to be why FR exists, to read everybody’s conversations and stick your nose into anything that interests you.
As for “troll”, which is another charged often leveled, the way that term is used around here is meaningless, not at all what the original “forum troll” meant — it’s just a way to dismiss what people say when you can’t figure out how to actually discuss something.
Thank you for your kind words. I will have to try harder to live up to your expressed opinion of me. There are times when “courteous” is the last thing on my mind :-)
