Our ancestors, Chinese and Jews did this throught history and the results were not good
Ignoring an issue never helps. If you are at the receiving end of racism find ways to deter that individual
The person subjecting you to racism has his own agenda of using you as e means too an end
Retaliation with goal of deterring the opponent is the only solution
I will disagree to this, as this is too simplistic in my 25+ years of experience in the west.
Those who are racist, will not be deterred by racism shown towards them, they will actually revel in it and fight harder, given that they BELIVE in race concept and will fight forever to assert their dominance in the race heirarchy. As the saying goes, never fight a pig in the mud : all that will happen is you will get dirty and the pig will like it, even if you get on top.
Remember, history also proves this true : racism is an invention of westerners. No other group of people have been racist, they have all been ethnocentrist. Ie, look at the Huns & Mongols in Chinese culture or the pre-islamic Turuska mlecchas in Indian culture, They were completely absorbed into the Chinese/Indian fold once they adopted the native religions,philosophies & customs. Ie, the concept of 'ethnos = best', where if you think like us, speak like us, believe like us, you are us.
Now look at the gypsies or Saami peoples - despite adopting religion, language, customs and being there for 1000+ years, they are still 'separate from us', because Europe came up with & believes in the concept of race - where to be us, you must be 'biologically us' - in greco-roman times, they had similar concept of ethnos as the rest of the world ( where people like Macedonians were considered greek, even though they were basically thracians who were hellenised by the Argead dynasty(Alexander's dynasty), who were 'true greeks'.
By the enlightenment era, this 'ethnocentrism' changed to racism, where they started to focus on 'being white/european' and then developed it into a psuedo-science in the 19th & 20th century.
In my experience, what works best with the racists, is to state these facts and disassociate oneself from racism, while being dismissive of the concept of race ( this is where science will help you, because race is scientifically a nonsense concept like palmistry and there is plenty of evidence of that).
The western psyche is, they want to take credit for 'civilizing the world' and as such, they try to claim every invention under the sun, but *not* the ones that carries a severe social cost to them. As such, they will try to prove that racism is not an european invention ( which too can be addressed by citation- there is scholarly articles on this).
Then you can throw in some 'calculated payback' to them, by speculating on the 'possible reasons' why Euros started racism by invoking race logic itself : Euros have predominantly recessive genes. What are recessive genes ? Genes that lose out to the dominant genes of their type. Ergo, recessive genes = inferior genes, as evolution is LITERALLY trying to weed out the recessive genes. Ergo, euros have a 'motive' to invent racism : to protect THEIR recessive genes by closed loop breeding.
Once you start to form the narrative ' Europeans invented racism-->racism is a bullshit concept--> Euros probably did this to protect their inferior genetic features' , THAT becomes checkmate for them.
The ones who argue ' superior/inferior' genes cannot escape the logic of 'recessive genes are inferior genes, you are people of recessive genes, so you invented racism to protect your recessive genes', neither can they accept it and one of three things happen:
a) they go silent
b) they go apeshit, frothing at the mouth and just going 'non-stop gaali' as their brain breaks
c) they quickly climb down from 'racism' and try to adopt a more 'ethnocentrism' mindset - and THAT is where you want them to be, because the western concept of ethnicity and ethnic relations is far weaker attachment and far easier to poke holes into.
