It is very easy to counter such accusations by making clear that it is a pacifist position you take. The arguments then will by around pacifism and the issues with that and not if you secretly support Assad. Try it some time 🤷
But since you avoided that term until I brought it up, I must assume you are indeed not considering yourself a pacifist, and then your rethoric falls flat and becomes a "if for some reason I can frame a conflict as class war then it is ok". And if you in turn apply that to conflicts like the Syrian civil war, then people accusing you of a double standard when it comes to your favourite dictator of the day might have a point.
