Okay folks, time to turn the heat down here, I think.
Everyone is entitled to express their own preferences, but not to question the right of others to express theirs. I'm not sure that's actually what's going on here, but it's worth being a bit careful when you're talking about what others think. And as saying "I don't understand why people x" is a statement and so doesn't invite a response it can come across as a criticism, so if you're genuinely curious and want to understand what others think and why, it is better to politely ask, while being ready to just agree to disagree. And if you're not genuinely curious, it's probably best to avoid talking about others and just stick to expressing your own views.
I think that's fair Red Queen. I think I should have focused on the effects behind the phrasing instead of the intent, instead of ascribing a motive where an unfortunate turn of phrase may have been the case. Also I used the word obsessive which I didn't intend to have a negative connotation, but I can see that was a poor choice of word. Apologies to RagnarokCzD for that, no insult was intended there.
I think it's important for people to note, though, that not being careful can lead on to a negative side effect of putting posters off contributing if they feel their opinion doesn't align with a number of the other opinions in the thread and this is generally a bad thing. It's just something to look out for in future when you think someone doesn't 'get it'.
I accept I could have made my point in a much more cohesive, persuasive manner and I'll attempt to do so in the future.
