Yes it is.
Your following paragraph doesn’t parse. I don’t know what you’re saying. But you appear to be making up what you think I believe.
For clarity: I think both the Tory and Labour immigration policies are racist, inhumane, and more to the point, pointless. You don’t stop migration at the English Channel, this side or that. What we see now on the English Channel is just a beginning as climate, economic and warfare processes accelerate. Treating boats on the Channel as a discrete issue is pointless. It cannot be separated from the context.
Labour could say something along those lines if they wanted. But they don’t, because they are trying to appear “serious” on immigration for the audience they are trying to impress. Not only that, once in power they will continue to act “serious”. By which I mean short sighted and racist.
