Opinion of people who cite Old Testament Mosaic Law verses as "proof" Christians are hypocrites

[Blue3]

Well, there are also many Christians who do constantly cite Old Testament law, and quote Jesus in ways they take as evidence.

Also the ethical problem for why God would supposedly create such ridiculous laws to begin with.

So what’s your opinion of Christian churches that say their focus is on the Old Testament?

Should all churches ignore all the moral commands and laws of the Old Testament, and just cite them as outdated historical footnotes?

(Putting aside how unethical and illogical having them in the first place is, or how bad that blood theory of atonement is compared to other interpretations of atonement)
