Etymology is biased

Etymology is quite biased against language isolates when it comes to "who borrowed the word from whom".

Speaking of etymology I often see people who have no idea what they're talking about say "Finnish and Hungarian are like brothers". Ummmm the languages at first glance hardly resemble each other. The have a handful of similar words but it's the grammar rules that causes most people to think the languages are related.

Also just because they're related doesn't make one easier to learn for a speaker of the other. English and Punjabi are related yet I don't see you having an easy time learning it.
