Nope, wrong. gogolmogol said it perfectly correctly: he said that marxism is a piece of shit (obviously) and Sprolicious tried to strawman that into "you're afraid of workers' rights."
You literally don't need to know anything about labor history to ascertain why that makes sense. Whether Marxism "has a lot to do with it" is irrelevant, because it's entirely possible that he hates Marxism as a whole but still supports workers' rights (and let's be real, who doesn't).
And while we're on the topic, this seems like that phenomenon of giving way too much credit of obvious and inevitable things (social safety nets) to Marxism and Marx. If things like this existed long before Marxism, influenced Marxism, and then Marxism merely proposed more of them, what's the significance?
