It is my opinion that it impolite to insert one's opinion about a thread when one clearly has not read the original post, the link on that original post or any of the relevant discussion about it.

Hmmm. Well, herein lieth your difficulty, Wacko. Imagine the following scenario:

*Obsessive bloke, well-known for starting thread after thread on his latest hobby horses, starts yet another tiresome thread, with some link or other which, tenuous though it be, lets him, opportunistically, fire up yet again, tangentially, one of aforementioned hobby horses.

*Other blokes who don't care much for tiresome-thread-initiator-in-question respond with a degree of derision.

*Obsessive thread-initiator immediately accuses his antagonists of "clearly not reading his link" etc.

*Antagonists in question have read his links (of course), but refuse to join in with Tiresome One's undignified attempted yo-yo-ing "you-didn't-read-it-yes-I-did-no-you-didn't-yes-I-did-it's-CLEAR-you-didn't-piss-off-Wacko". It's like this, Jack. You accuse me of not reading your links and you have disqualified yourself until the end of time from finding out whether I did or I didn't. That's your silly game, not mine.
