Is it normal i don't want them at my birthday party?

I have a big milestone birthday coming up and with family members have a party planned which by choice has become also a family reunion. I've been really looking forward to it until yesterday when one nephew I haven't seen for a few years posted some very right wing racist and sexist comments on facebook, emphasising one recent case where a muslim refugee attacked his partner. I think he was channelling Pauline Hanson, Australia's version of The Trumpet, except she goes on and on about muslims, not mexicans.

I responded by pointing out that none of the men who've sexually abused/raped/assaulted me were muslim and he responded with some bullshit about how many men are victims of "spousal abuse". I'm almost 100% certain his brother and his mother (my sister) support his islamaphobia and now I don't want ANY of them at my party.

My daughter says to ignore it (she blocked the other brother on facebook ages ago after similar posts)and continue sending out invitations to them as if nothing has happened: a mate says it's my party and I don't have to invite people I don't want to spend time with.

What would you do in this situation? Assuming you don't agree with reactionaries of course: if you're a trump or hanson supporter I'm not at all interested in your views on this or anything else.
