Islam is a religion of tolerance and peace

We all know that Islam is a religion that promotes tolerance and peace. But why do muslims in Thailand like killing buddhists? And why do muslims in Nigeria, Indonesia and Egypt like killing christians? And why do muslims in India/Pakistan like killing hindus? And why do muslims in the Middle East want all jews killed? And why do many muslims hate each other so much that sunnis and shiites are forever killing each other?

It’s all very strange. Perhaps there are some muslims who have not understood that Islam is a religion of tolerance and peace.
