As for the "forced abortions" and "Death panels"... it helps to note where those claims came from.
Death panels came from two issues, one being the restrictions of benefits which would "sentence" people to death who paid their entire lives for health benefits. You see this in the UK, there is some ageism in treatments. The second is in the "end of life counsling" which people find disturbing because they beleive these should be things planned for since many elderly are a lot more suggestiable when younger. Sensationalized term yes? More so then normal? No.
As for the forced abortion claim... that came from the fact that Obama's science Czar actually coauthorted a book that said the government would have to forcibly abort and sterilize people. A position which he never denounced "which must mean he's for it" by your logic above, even more so since he can actually be linked to the book unlike the people your condeming.
Of which, this bill would obviously be a first step since you would need control over healthcare before such a thing could happen. Once again an exageration i bad taste? Yes. One that's worse then the normal political scene? No. Attacking peoples past positions and their advisors past positions is a norm in politics. It's just this time he was tied to something particularly bad.
