Mainstream capitalist ideology is responsible for and compatible with a high degree of anti-fascism. This has very little to do with 'fascism,' that might not even be present, and more to do with the role of fascism in the self-vindicating mythology of modern liberal democracy.
It belongs to liberalism, or that part of capitalism which merely wishes for 'class-collaborationism' and to safeguard capitalism by ensuring mutual consent of its members. It necessarily serves to 'dilute' or oppose radical political trends that partake of it, or dilute the 'negativity' and 'hate' in a movement, such as to preserve the given social coherence. Positive sentiment and relations are encouraged in the present, a barricade against radical opposition to the present system of relations. Hence, if the movement against 'fascism ' is to be characterised, it is in these terms. However, it can often merely chase shadows, as, like a capitalist corporation that is forced relentlessly to produce new content even without a spur, it tends to 'manufacture' fascism even when it isn't there in order to maintain its empty sense of relevance and urgency. This is because it is selling a product, one that aims to dilute or undermine radical opposition to the system and which hence has to be kept going compulsively after some perceived 'fascism.' Nonetheless, this merely furthers its liberal nature, and gives it no other real basis.
In any case, what about 'fascist' movements? Fascism was not always a simply 'racist' movement. 'Racism' at the time characterised many nations. Further, the desire for a 'racial' nation is not one unique to whites - it is also a property of Judaism, known also for its racial warfare and belief in a 'chosen people,' and exists in many forms. Hence, racial nationalism is not by itself fascist. Fascism is an ill-defined term in some ways restricted to a 'concrete movement' or period, and hence is often reduced to something simplistic like 'racism.' It would be difficult to have a coherent movement against it. 'Anti-fascism' lives on because the capitalist establishment has declared Nazism the ultimate embodiment of its own fears, and so-called 'revolutionaries' have risen to the task of opposing what the system tells them is most evil. Of course, the system also considers revolution to be evil - but then, modern anarcho-communists don't really care about revolution, so long as transsexual people are given the appropriate gender pronoun and nobody seriously criticises Israel.
However, the spectre of 'fascism' nonetheless represents a force resistant to 'liberal democracy' and 'anarcho-communism,' a vision of nation with a sense of direction that unifies it. If one makes a dichotomy of anarchist and 'non-socialist' fascist, there is no room left for the Marxist or for socialism; the socialist aim of a guided society is wholly attributed to the 'non-socialist' fascist, or in any case is ignored structurally. Hence, such 'anarchism' is highly reactionary, in the end, and it is ultimately just a variant of liberalism. The more that liberalism is allowed to proclaim its ultimate emptiness and lack of direction as if this is substantial and benevolent, the more is conceded. The leftist panic over Trump, to which the obvious corollary was supporting Clinton, is one example of 'anti-fascist' panic being obviously used to undermine radicals and incorporate them into liberalism. Nonetheless, fascism is mainstream capitalism's very own vision of the devil, and opposition to it is nothing notably striking - further, this opposition generally cites the same reasons as the capitalist establishment. Mainstream capitalism is responsible for and compatible with a high degree of anti-fascism. This has very little to do with 'fascism,' that might not even be present, and more to do with the role of fascism in the self-vindicating mythology of modern liberal democracy.
Hence, caution is advised around this subject, for, 'the worst product of fascism is anti-fascism.'
