It's not going to keep foreigners out... It is so tough for me to get how anyone would think that.
I don't care. It symbolises their desire to keep foreigners out, which triggers the left, especially the political class, because they are banking on the vote of nationalised foreigners to secure power.

Why do you care so much? It's not your tax they're wasting.

There are so many better solutions than a wall.
I'd agree with this. Trump probably knows it too. So what's the real purpose of the wall?

It's bad that it takes so much focus from real issues.
Maybe this is why they want to build it. Everyone cries about the wall while USA continue their globalist agenda.
