It fucking is, it's the reason why jews don't recognize the Bible and have persecuted and slaughtered Christians for hundreds of years. Because the Bible literally says they are bastardized mongrels and God hates them for it.
Exodus 34:16 - And thou take of their daughters unto thy sons, and their daughters go a whoring after their gods, and make thy sons go a whoring after their gods.
Deuteronomy 7:3 - Neither shalt thou make marriages with them; thy daughter thou shalt not give unto his son, nor his daughter shalt thou take unto thy son.
Leviticus 19:19 - Ye shall keep my statutes. Thou shalt not let thy cattle gender with a diverse kind: thou shalt not sow thy field with mingled seed: neither shall a garment mingled of linen and woollen come upon thee.
Daniel 2:43 - As you saw the iron mixed with soft clay, so they will mix with one another in marriage, but they will not hold together, just as iron does not mix with clay.
Ezra 9:1-15 - Now when these things were done, the princes came to me, saying, The people of Israel, and the priests, and the Levites, have not separated themselves from the people of the lands, [doing] according to their abominations, [even] of the Canaanites, the Hittites, the Perizzites, the Jebusites, the Ammonites, the Moabites, the Egyptians, and the Amorites.
1 Kings 11:1-43 - But king Solomon loved many strange women, together with the daughter of Pharaoh, women of the Moabites, Ammonites, Edomites, Zidonians, [and] Hittites; (protip: Solomon fell out of grace)
Here's on about 'muh equality':
2 Corinthians 6:14 - Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
And here's on one race-mixing and multiculturalism:
Joshua 23:7 - that you may not mix with these nations remaining among you or make mention of the names of their gods or swear by them or serve them or bow down to them
And now you can fuck off back to Something Awful, you 'atheism+' SJWs.
