I think we are getting more intelligent as a race, but humans are devolving quickly getting weaker by the day. If you look at how easily offended and lazy people are becoming it is depressing, especially in the first world. (I know I am generalizing, ofc there are tons of strong hard workers left)
I believe this is true. I can't help but think social media, in particular, is responsible for people being offended by everything. The anonymity and the ability to cut others down without repercussions seems to embolden people to act with disrespect toward others and a hypersensitivity that leads to being overly defensive when confronted with an idea contrary to their personally held beliefs.
It is unfortunate 'ignorant' has such a negative connotation. We all think or say things that are ignorant. It isn't possible to view everything in life from a non-biased, educated point of view. It's just unfortunate that people are quick to stick to their guns when it comes to their opinions, even though they may have been exposed to something that can open their eyes a little more.
