Have to agree with this. Honestly if it was all about love and tolerance, without even the occasional deviation to enhance the story line, I have a feeling we'd be looking at a G3 show all over again. The key difference between FiM and the failures before is that the show actually relates to real life scenarios, where things aren't always perfect and conflict does exist.
I do think we're lightyears ahead of other fandoms, when it comes to acceptability and conduct, but not without the occasional slip ups. Things are bound to happen, and some person’s wrong actions can't hold the whole community accountable.
