So, thanks for the tunnel story, it was needed to straighten me out. I bet you felt pretty good, thinking you showed me. All of your Libtard buddies were likely cheering too. LOL I'm a little bit impressed that it's not from one of your usual Libtard sources, so there's that, bravo.
You could have done what most idiots would do and said, (use a Stallone voice here) "What about tunnels, dude??" said the moron "Can't they just use those, dumbass?" I'm cracking up just imagining you saying that.
Just to break it down real simple for you (read it very s...l...o...w...l...y, so you can understand) The comment 'they'll just blow a hole in the wall,' for those who don't need everything explained like they're in second grade - it's suggesting that some future dumbass President, like the one who just waddled out of the WH, might do exactly what Train ridin' Biden did in his first days in office, reverse every policy and directive to open the border up again. It shouldn't be a concern, because who would purposely want to put so many citizens at risk? But we are talking about Libtard drones that seem to be hellbent on destroying America, and their simpletons supporters like you. So, it's sadly must be planned for the realities of idiots in power.
