Why do people say every single religion is violent when Buddhism and Jainism, Hinduism teaches non-violence or Ahimsa?

Religions creates faction. These cults obssessive believer refuse to tolerate creates tension and caused those violence we see today.

"If you meet the buddha on the road, kill him."

Wisdom is not something you can just read on text book.

Those religions have also been used to justify violence. So has every religion with a large amount of followers.

They're setting the bar low.
They also claim every single nation was founded by invaders, using slave labor-. Because theirs was.

Religions are not very useful to powerful people who play God with people's lives.

Abrahamics don’t like to be reminded of what they’ve done.

Any group will fight back if threatened.

People don't always follow what their Holy Book says. There are Buddhists who were responsible for massacres against Rohingya and Tamils.

Some folks like to generalize.
