I wrote "Iains merely acknowledged the work you have done."

You replied "Iains has made clear where he stands on who should and should not have a say on these matters, just as he has on what he thinks of those who disagree with him "

No mention of his politics. It reads as if you are commenting on his reference to your collecting work.

Perhaps, as other people have already suggested, you should take a little more care before you post.

Finally though I might disagree with much of what Iains posts about politics, I will defend his right to post it.
