alt Hacker NewsI can already do functional programming like map/reduce in C# tho. Not sure what the LISP argument is. Spolsky was saying there's a perf benefit in there somewhere but I'm not seeing how unions give me that.

You have at least two options:
1. Argue from ignorance. Never try unions in any other programming languages and completely disallow their use in C# codebases that you participate in.
2. Try them out and adopt an informed opinion.
You may even choose to remain in ignorance until someone wastes their own time trying to convince you. But it isn't my job or desire to teach someone who won't put in the effort to learn for themselves.
