Etymology is biased

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

I often see people who have no idea what they're talking about say "Finnish and Hungarian are like brothers". Sure they have a handful of similar words but it's the grammar rules that cause 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 (Indo-European languages) yet I don't see you having an easy time learning it.
