Ted Nugent is portrayed on Fox as way over the line in his remark about Obama. It is NOT endorsed by the right, or by conservative media. And Nugent himself was genuinely remorseful and apologized immediately because he quickly realized it was over the line.

COMPARE:
Bill Maher joking about Sarah Palin as "the MILF vote", etc. : NO APOLOGY
Kathy Griffin who held up Trump's severed head in effigy: NO APOLOGY (but incredibly, whined that >>>SHE<<< is the victim).
David Letterman joking about knocking up Sarah Palin's Younger 15 year old teenage daughter: NO APOLOGY.
Mika Brzezinski and Joe Scarborough's constant insults and personal smears of Trump: NO APOLOGY.
The many political DNC officials who have made comments about how people should attempt to kill MORE Republicans: NO APOLOGY.
