Will you apologize to all if found wrong by history?
Apologize for what?
The first paragraph (about ObamaCare being a stepping-stone to socialized medicine) is supported by actual comments made by lawmakers. The last portion is saying that socialized medicine doesn't sit well with me and therefore is personal opinion -- nothing to apologize for there.
The second paragraph is statement of the fact that Art. 1, Sec. 8 does not delegate to congress the ability to institute socialized medicine as it does, say, instituting an Army or Navy or Post Office. The parenthetical simply acknowledges that the more we treat the Constitution as non-binding or optional the less relevance it has in actuality.
