I agree, both should have been charged. Only one was. You could argue that the MP is making the greater offence as he/she is in a position of authority.
Thanks for the info. What disturbs me most is the polarization and increasing intolerance of different/opposing ideas and opinions. I'm referring to "slit their throats" kinds of reactions and "set [it] on fire". There's no "lets agree to disagree and meet half way". No compromise. That's seen as weak.
