There's a lot of truth in your first paragraph.
The comments on any crime by a non white go through the roof on social media compared to a similar offence by Buckfast Billy.
And racists often hide in plain site, using the excuse that all ails are due to the influx of immigrants, without ANY real proof. The fact is, the vast majority of non UK citizens that arrive on our shores do so legally and contribute to, not take from, our economy. Of those who do make the perilous journey, ask yourself this. Would I risk my life if I thought I could survive properly where I was?
Also. I feel you're getting this backward.
Yes. Our resources are finite. But they would be less so if our taxation system was fairer.
Look not down at those who are trying to survive but UP at those who horde their wealth and their greed demands they want even more of what they can't possibly spend.
