my gaydar failed as well. I thought it was a bold acting move when he kissed the men on house of cards. should have rung the bell there.
He is a great actor, and plays men of Strength well. That said, he did twinkle when not playing a character. I have to say that I like him, even suspecting he was gay.. But if this (these) allegations are true... he may be done.
Now would be the time for Feldman to come clean with all he knows, time to put up or shut up.
