Defending? I call it explaining. But I do it for those who are interested in the truth.
You, on the other hand, may be quite content to rant and rave that FDR "expanded" and "twisted" the Commerce Clause to suit his agenda. This is what you've heard. This is what you believe. This is what you repeat.
Those who disagree with you -- well, you smugly quip, "They're 'defending the FDR agenda'".
"Explain" away kiddo.
Once again you've outed yourself..
