Superdude, any info on Manchester?

The first two were not labeled terrorist attacks; as far as I'm concerned it's just semantics.
And speaking about motivations: Do we already know the motivations of the Manchester killer? Was it Islamism; or was he a lonely MRA with a crush on Ariana Grande?

A few weeks ago there was a bomb attack in Germany, on the football team of Borussia Dortmund.
Shortly after, social media filled with comments against Merkel's immigration politics; because lots of people assumed it was an Islamist attack.
And then, it turned out that the perpetrator was a white non-Muslim European who had acted out of greed. He wanted to disrupt the stock market.

I'll reserve judgments about the Manchester bomber's motivations until I know the facts.
