Michael Lohan -- Gets Off SUPER EASY In Domestic Violence Case

It seems like Lindsay Lohan was treated like a mass murderer compared to the sentence Michael Lohan got for allegedly beating his ex-girlfriend last month ... because unlike his daughter, MiLo was NOT sentenced to the slammer.

Lohan -- who was accused of beating the crap out of his ex-GF Kate Major back in October -- appeared in a Tampa courtroom today and pled no contest to 4 misdemeanors ... involving an incident at Kate's apartment last month, in which he allegedly got violent when she refused to perform oral sex on him.

In exchange for his no contest plea, Lohan was sentenced to 2 years probation and ordered to spend 4 months at a residential treatment center. Lohan was also ordered to complete a domestic violence batterer’s intervention program ... and he's been banned from having any contact with Kate.

Meanwhile, Lindsay was sentenced to spend 30 days in jail after she violated her probation in a case stemming from a non-violent crime.

Seem fair to you?
