Why do people who haven't researched religions put down a religion from the rumours they heard? We aren't in grade 8 anymore. Do the research, then discuss using the knowledge you gained from your research.
For example if you have questions on why certain people eat pork, why don't you ask the person practicing it? They out of all people might give you the best answer.
Educate yourselves my friends before hating. We are ALL brothers and sisters in this world, and don't listen to whoever tells you different. Don't fight those who could have been your best friend in 5 years.
We all have violence and aggression - it's our human nature. But don't take it out on your potential friends/ brothers in law/ mothers in law, or person who maybe could save your life someday ahead, etc....
