Why do you think some people are so easily offended these days?
This question was kinda funny to me because everyone in my country (Nigeria) are on default anger mood, so when you want to ask anything, you have to apologize first. Let me give you an instance.
MR A: Sorry Ma, what is it by your time?
Boy A: I am sorry Sir, where can I get the book.
Should I blame the global warming for this, since everywhere is naturally hot so people easily get offended. An average citizen is always offended everyday, they wake up in the morning and when they don't get served food on time, they are offended, on their way to work. They meet traffic, another anger and when their boss try to push them way beyond their limit, of course you know they will be vexed. Lets use steemit as another instance, someone read your post, comment and ended up upvoting only his comment, won't you be offended?
Generally, the situation in those people's life do get them offended at every little thing.
