There is not relation between Albanians and Berbers, some Serbs on Internet with no knowledge make this propaganda, they are as lost as the Muslim fundamentalists calling Slavic people slaves.
E-V13 can be IE speakers why, not, because it would crush the dreams of the R1b West European supremacists! Have u heard of mother language and mt DNA. How come now people that are not R1 speak IE, well same goes for back then.
The fact of the matter is E-V13, I1, I2b,I2a,G2a,N1c and majority J2 and E-M123 are in Europe long,long, long before R1, but some racist from Western Europe can not live with it
Albanian is placed as an Indo-European language. It's a branch by itself, sharing its branch with no other language. Questions is whether there are influences of Afro-Asiatic languages (Egyptian/Coptic, Berber, Cushitic, etc). Logic is that carriers of haplogroup E could not lose all words in their movements from north-east Africa, across the Middle east, to Balkans.
Of course, this is very complex issue, and in such subjects always appear problems of simplifying. So often Western Europeans and Balkans peoples (Serbs, Bulgarians, etc.) go by the logic of simplifying, and they does not mean anything bad. The facts is that E-M78 is family tree for subclade E-V13 (as subclades E-V12, E-V22, etc), and origin E-M78 is north-east Africa (probably Egypt).
You can see Albanian and Arbereshe linguists and researches find link between Albanian and some Afro-Asiatic languages. For example there is a book:
Giuseppe Catapano,
Thot Parlava Albanese, Bardi Editore, Roma 1984.
He compared the Coptic (Egyptian) and another languages with Albanian.
You have more links in Albanian and Italian, this is one example:

Albanians themselves investigating and it's not taboo. And why? There are Albanians who seek a conections with the Ancient Egyptians and love it.
And all it is right. Seeking the roots is one of the most interesting things for human beings, and it serves this wonderful forum. Again, problems occur in simplifying. But it's hard to avoid in threads and discussions in forums. It's hard for people in every message, reply, topic, to explain for a long time, and simplification always will be exist in Internet.
