Mmm, more like, I wanted to contribute without reading some/all of the thread. When that was pointed out you took umbrage when questioned whether you had read at least the original post, instead of saying 'sorry I hadn't read that/the whole thread' you went on the offensive.
We've all done it, especially in longer threads,
and no doubt will again in the future,
but if it is pointed out that what you/I say has already been mentioned, possibly multiple times, just take it on the chin. Just my Pov, Yvmv.
