The MPs making obscene gestures at Sarah Champion and other women in the Commons are the backbench nonentities.
There is a scene in Paul Thomas Anderson's Boogie Nights when porn star Rollergirl (played by Heather Graham) is at college, and a male classmate taunts her by making a fellatio gesture. Later on, the classmate is insulting her again and Rollergirl helps to beat him up, memorably stamping her skates on his head. Interesting that even a porn star character is shown to possess a sense of outrage at degrading inappropriate sexual gestures. Perhaps certain British male MPs need to see Boogie Nights for some tips on how to treat female MPs with respect.
