If they 're not related , they 're not all Slavs .
I'm deeply disturbed by your views. Are you trying to offend people?
I don't understand this question., Is it about friends and relatives in general? I'm saying that Slavs have plenty of kins because they have a big family.
Stereotyping is not good because it leads to wrong notions about a particular community and on that basis, discriminating against it. Learn more about the people you're commenting on and you might find that they're just the same as you and me.
