They actually cannot implement it. They voted that antifa is a terrorist organisation. But antifa is not an organisation and they cannot do that, because in the Netherlands only judges can decide what organisations are terrorist.

Yes, he made a very dumb remark. I do not think he apologised for it and he should have.

In the Netherlands, some in the far right actually are saying that foreigners (especially muslims) are anti-gay and therefore should not be a part of Dutch society or be deported.

Edit: I do have to say that they also say that women are suppressed by foreigners. And that at the same time, they do nothing to protect the rights of women and LGBTIQ+ people. Apparently, they are only concerned with that when they can use it against foreigners.
