Not with that attitude you can't. Racists aren't (usually) racists for the fun of it. Racists are racists because they feel threatened by or lack sufficient exposure to / understanding of other races. If your goal is to cure racism, then making racists feel even more threatened is probably the least productive way of going about it. Instead, the trick is to befriend them. Show them that there's nothing to fear. These…
When has this ever worked at scale? All major social change to end oppression has been associated with large scale disruption and unrest. How nice it must be to be in a group with power, where even if you are an unrepentant asshole and deny the humanity of others, those other people are obligated to be nice to you.
Re: whether or not it works at scale, it seems to have worked for Irish-Americans. It took awhile between the height of Irish immigration and the present day, but unlike in the 19th Century you'd be hard-pressed to find anyone unironically demanding Irish people to be deported or claiming Irish immigrants are stealing jobs. Similar deal for other previously-persecuted European immigrants and their descendants (Italians and Germans both come to mind). Asians are getting to that point, too; not really free of discrimination/prejudice, but even my most hatefully-racist acquaintances seem to at least tolerate their existence.
None of the above groups (to my knowledge) were all that socially disruptive (at least not intentionally); instead, they gradually integrated and blended with the existing demographics. Instead of Irish or German or Italian or English or French or Polish or Russian or what have you, we ended up with kind of a blended European demographic. I have a feeling Asians are on track to be part of that, too, and end up in a sort of blended "Eurasian" demographic. We ain't quite there yet, but I'd give it a couple decades before we are.
