Well there is no denying that Turkey's invasion of Byzantium on the pretext of it being an Islamic Conquest, is a farce, a deception and a lie. Regardless on how you try to spin it, the turks used Islam to gain legitimacy for conquest of Byzantium which it would otherwise not have. Turks don't belong in Byzantium, they belong North of the Caucus mountains where their ancestors and they themselves come from. Arabs never drove out the Persians from Persia and occupied their lands. The Moor's didn't expel the Spanish or Portuguese from the Iberian Peninsula and convert all Churches to Masajid.
Nope, turks conquest of Byzantium shows political agenda, the depravity to have the Khilafah and being recognized in the Islamic World. Something very similar to what their cousins, the Khazars did, when they embraced Judaism. Doesn't matter how you spin it, Caucasians have always been very agenda driven, ego centric that converted to other faiths like Judaism and Islam, out of political expediency.
