You might already understand this point, but I thought I'd mention it anyway.

Because we're social animals and most people don't have the ability to simply ignore harsh/insulting/whatever words directed at us.

It may well be possible to develop the ability to ignore such words, but if it is, that's an ability that would take a fair bit of time to develop, so is out of the reach of most people right at the present moment.
