Can I request you explain again because it seems to me that rather than sayingLast sentence wasn't directed to you. I meant I will explain more patiently.
"looks similar",
"speaks a language with a common ancestral tongue", or
"shares a distant common lineage"
you seem to be saying
"is the same race".
Maybe it's because you're using ethnic terms synonymously with more specific cultural or linguistic terms. That might be something to avoid lest you repeat your earlier error of saying Scythians were genetically Germanic.
