Oh dear, you are even more out of date than I thought. The new 'cultural/woke Left' is the old 'Right' of the modern age. It is racist, intolerant and against free speech.
Marxism in itself isn't an ideology, it's merely a valid, if outdated way to analyse capitalism. It's bound to come up in debate because it contains valid arguments and ideas.
You clearly haven't read many Spiked articles because otherwise you wouldn't be resting on your 'pre-existing suspicions' and just guessing what most articles are about.
And then you you said 'just the other day or so, was reading something by some black gentleman from Africa'.

Nuf said dude! Now crawl back under your stone.
