I think its to do with personal opinion and up for debate - a couple of links on the internet is not concrete. Im happy for you to disagree that 'heterophobia' exists but Im more interested in your reasons not articles and blogs. Remember "homosexuality" once didnt exist...

Also just to add homophobia is more common because its in favour of social norms whilst heterophobia is the exact opposite - making it even more irrational.
