I think you've completely misinterpreted my comment!
You're absolutely correct - M&S is just a brand, & the point of this thread is to allow people to voice their (equally valid) opinions on it, whether positive or negative. So I completely agree that it's a bit daft to get upset if someone trashes the quality of their knickers!
Personally, I couldn't give a toss whether people think M&S is great, dreadful or (IMO) somewhere in between. I have no strong feelings whatsoever about the M&S brand - I have liked some Autograph clothing lately, & I do still buy some underwear there, but that's about it? So perhaps you're confusing me with another poster who's a more devoted fan?
What HAS annoyed me is all the shit that people are hurling at each other on this thread, where they seem to think that only their own opinions can possibly count? THAT'S what I mean about "nit-picking, intolerance & barbed comments" - some of which you yourself have been on the receiving end of, from more than one poster ...?!!
I mean, so far people have called each other clueless, unstylish, without fashion sense, snobbish, dismissive, rude, ridiculous, liars ... oh, & "Mums Bitchers"??!!! And that's not even all of it! Admittedly, some of these were in response to rudeness - but I find it all a bit unnecessary & wearing ...
In contrast, this has been a delightful & fascinating thread to read - & not an insult to be found!
