Do you think this is true?

Absolutely not, and nothing you said matters in the least.

Deaths don't mean shit when you look at the prevalence of a violent ideology, what the fuck? Which is the bigger problem, one religious attack that kills 40 people, or 35 religious attacks that kill 1 person each?

The first one may have killed more, but the second one shows a serious problem where a violent ideology has spread amongst a community.

The number of people dying is only indicative of how the committed the attack. Islamic terrorism having a higher death count means there are a handful of people who plan their attacks, and Right-wing terrorism having a lower death count means there are a lot more people who just shank 1 or 2 civilians.

While I do care for the innocent lives taken, I'd much rather look at actually relevant statistics regarding these matters. I care about the number of attackers, not victims. And as far as I'm concerned in the US, violent (alt)right-wingers are a bigger problem.
