Michael Lohan wants to set the record straight about everything ... from Lindsay's upbringing to Dina's allegations of abuse.

When it comes to claims that Lindsay witnessed Michael's alleged abuse firsthand, Lilo's dad says this never happened ... and his ex-wife Dina is "being a hypocrite, as usual."

To set the record straight, Lohan adds:

    "Her entire family are drug addicts. If Dina wants to talk about abuse, she should look at her own family."
