But could it be that some people mistake hard truth for a lack of charity?
It is certain this happens. It happens much more easily in a medium like this one than, say, in a live, face to face conversation.
That said, whatever is POSSIBLE for others when reading your words, is ALSO POSSIBLE for you when reading the words of others.
Again, sit tight, chill out, and let if proceed naturally, sharing what you know with those here - and letting them share what they know with you. Like my point above, it is a two-way street.
Godspeed.
