Don't say things like that. One might almost think you consider such things acceptable.
Alhumdullilah my masjid has an incredibly strong Kurdish community. They are great muslims and a blessing to have in my area.
This is VERY important for every Muslim to know and say. There have been Muslim Armies and Countries, especially in the Anatolia region which incorporate the Star of 'Da'ud' (as). Let's remember Da'ud (as) as our prophet. He is a Muslim. And if I remember correctly, It is a condition of faith to believe in all of our Prophets. It is only in these times we have forgotten our own heritage.
We can and should use the Star if we wish, it is our symbol.
