Popularity =/= the right thing to do

It always seems that almost everyone loves to jump in the bandwagon. Why did it seem to be the way when it comes to popularity that it can be too obvious to tell when it's alright to do it or not. Havent people forgot the fact that popularity can lead to terrible thing. I mean what just happened to knowing thing before joining in the bandwagon when it comes to popularity. serously just because it's popular doesn't mean it's complete right to join in. It just levels up to certain things like getting drunk at the bar, making fun of religion, and other source of popularity which lead to bad things

Remember of what Albert Einstein have said, "What is right is not always popular and what is popular is not always right."

Does it always mean it good when it comes to popularity?
No
