It's called democracy: anyone, including them, has the right to form their own political party. At the same time, everyone has the right to openly express their opinion about them (freedom of speech). And, of course, nobody has to vote for them.
Let them participate if they want to, they'll probably end up empty-handed at the end of the next elections anyway.
I'll be voting for a different party, one that doesn't want to legalise despicable acts.
