Don't let the feeble minded get you down.
You have to think to yourself, if that's what his opinion is then let him have it.
If everyone stopped posting because they didn't like what one person said, then PPRuNe would be a pretty quiet place.
I log in, read the posts, and if I don't like them then I move on.
I have learned so much over the last few months since discovering PPRuNe and it's only because of people like yourself who bother to take the time out to answer questions, post useful information etc.
There are a lot of good people within this group and to stop posting would be mad.
If certain individuals are becoming a pain, then just don't reply to any of their new topics.
