George,
We are all entitled to our own opinions & to voice them in a civilized way.
In my experience if you hold strong views in any subject you need broad shoulders & a thick skin.
If some one is "sensitive" to humour, criticism, correction, ridicule, disagreement, then perhaps they shouldn't voice the views that bring forth those comments.
When in a hole stop digging, don't ask for a bigger spade !
I agree with most of what you say but how is any of that helpful or relevant to the OPs thread about a SIP Turbo welder? It's off-topic clutter. I blame Weldequip for stirring it up by posting a definition of antagonism. So if I challenge him on technical points about the merits of a SIP Turbo welder, it's antagonism is it? If anyone is in a hole, it's Weldequip for apparently indicating that he disagrees with the buyers guide.
