Seconding this!

difference is political/social/cultural rather than linguistic....

(you try tell Serbian ppl they're speaking a dialect of Croatian, or a Hindi person theyre speaking a dialect of Urdu... stabbed ... ask them if they understand the other, tho, they'll say of course, it's the same language you moron... stabbed)

(linguists have never agreed on any linguistic criteria that would define the difference)

TL;DR you're getting stabbed
