Re: Karbala
1) marriage with mehram was allowed (marrying your sister becomes legal and islamic)
2) chicken declared haram 3) Gay marriages allowed 4) Assult on Madina Munawarah (no pyares in masjid-e-nabwi for 3 days) 5) thousands of sahaba, tabaeen (one how saw a sahabi in a lifetime) killed.

You're kidding me right?
