Now and then, I see people being rude or condescending to other users, mostly in a subtle manner, but it shouldn't be like that. Except that the person is being a jerk or just inhumane, there's no need for that.
I understand but sometimes there is also wrong in our perspective the way we read and understand them.
While it could be a normal reaction and words to them and in their culture but with yours, you think that they're being rude and condescending to others.
I also notice that but we also have to understand maybe that's how they are expressing themselves in a way that we think we're offended. But in no means, that's just normal to them.
In some people, the obviousness of their rudeness is there and we can't stop them from being like that.
