Here's what I think.
It's absolutely fine to have an opinion about something and express it (to a certain degree). Heck, I admit I'm not a big fan of logo printed bags either. But here's a thing. Why dwell on it because you might end up offending someone who actually loves the look? Not to mention creating a negative vibe in the forum. I also don't see the point of saying "I'm gonna go back to Chanel now" while Chanel also has their classics and has a certain designs that are loud. Just like Dior. Plus, it's not the case that Dior completely stops producing the classic stuffs either. MCG has some really nice subtle designs as well, like the studded bags (e.g. LD and camera bag) are gorgeous!
Anyway, beauty is in the eye of the beholder right?
I have read the whole thread and I don't see anyone's comments as being out of line... that is, unless I don't understand the forum rules? (averagejoe?) If you had posted a reveal, there would have been no debate and I am sure everyone would have just said "congrats" and "enjoy". However, your initial post essentially stated you were on the fence about the bag. This unsurprisingly lead people to give their honest opinion, whether good or bad.
