When the very thinly-veiled insults start to fly it means QED and good bye.

I don’t need to thinly veil anything: most people who constantly bang on about immigration are racists.

Those who talk about migration from a structural perspective: infrastructure costs, capacity, etc. have legitimate grounds. But, I would hope they have a decent understanding of the costs and strategic planning required to build infrastructure for a growing population and they weren’t just using this as cover.

Those who discuss the root causes of migration and think those should be resolved from a human dignity point of view, also have legitimate grounds.

Yet, those grounds are nearly never discussed. I don’t see any mention of those in your comments either.
