That's about as strong a statement (in the context of the previous verse 1 Tim 5;10) that a widow who re-marries is "against Christ." Not the Protestants' favorite +Paul's verses, eh?
What are you talking about? Is this a shot about plain meaning? If so, then I would just say that our God is also a God of common sense, and that any interpretation that all young widows are automatically against Christ fails common sense and also the rest of the scripture. When any two verses contradict on plain meaning, then proper interpretation is necessary.
Unless you can show me otherwise, in context (as I said), +Paul is saying that "real" widows do not re-marry; in general, that widows and widowers should not re-marry.
