Why do you want me (assuming you're talking to me) to "defend" these things?
FWIW, I think the talk of a no-fly zone was silly. I recently started a thread saying that we should cut our defence spend to £0 so that should give you some idea of what I think about arms dealing.
I'm not particularly interested in Quintin Hogg; as we have seen, Hogg is not alone when it comes to being a prize **** at Westminster. I don't know why Cameron wanted to make him a peer. Perhaps Hogg has done all sorts of great things. Frankly, I don't know. The moat situation was obviously ludicrous but it's clear that huge numbers of MPs used the expenses system to supplement their parliamentary income. Whether they played the property fiddle, downloaded porn, gave family members a summer job or cleaned their moat is pretty much immaterial but I don't think we're suggesting that any MP who ever made an expense claim against the background of that systematic convention should be barred from the Lords are we? Maybe we are. Or maybe we're just choosing one example because we have an irrational dislike of rich people.
What I find hard to defend is the sort of sad and puerile point scoring that characterises political debate.
