The attitude of Islam toward using violence against non-Muslims is clear. The Quran says, "Slay the idolaters(Non-Muslims) wherever you find them. Arrest them, besiege them, and lie in ambush everywhere for them. If they repent and take to prayer and render the alms levy, allow them to go their way. God is forgiving and merciful" (Surah 9:5).
This is the attitude of Islam, can any Muslim in this world reject this? The answer is big no, caz its written in Quran. Now is it wrong to be wary of Muslims?
Rebirth is not found just in Hinduism, but its also found in Jainism & Buddhism. Infact its the way of life for Buddhists.
