If Islamophobia is a racism that is based upon “perceived muslimness”, then Atheistophobia is a racism that is based upon a perceived rationalism.
If you are rational towards religion and critical of its beliefs, then any violence, abuse and counter-criticism is racist. If you hold secular humanism as your belief and people criticise or attack your non-theocratic lifestyle, then they are being racist.
This is to pay back in the same coin all those idiots and ignorant people who peddle the idea that the word Islamophobia is the correct one!
It is a misnomer.
