It is great to be proud of one's own religion and I do not want to take away that right from you. Now the examples you quote "Geeta" and "Ramayan"
"Geeta" - Said to be written by Lord Krishna (due respects) who was the mastermind in the whole "war" in Mahabharata. The war was faught only for the "throne"
"Ramayana" - The whole war was faught for a "woman". Well Hanumanji had reached Lanka and he could have simply carried Sitaji back. But no, Lord Rama (due respects) had to fight the war and create bloodshed.
If you see anywhere in the world people be it from any religion are involved in similar activities. But muslims are foolish as they try to do it openly in the name of religion and have made themselves soft target of other religions. If the incident that happened in the US university involving Indians had been identified as been done by Muslims, they would have been dubbed terroists. But here they are called planned executioners.
