What is a good word to describe someone who is talking down to you and thinks your decisions/actions are wrong? [closed]

With regards to talking down, a possible word is patronising

treat with an apparent kindness which betrays a feeling of superiority.

She's a good-hearted girl,’ he said in a patronizing voice

or condescending

having or showing an attitude of patronizing superiority.

An example of condescending is a parent who speaks to her grown child as if he were still a toddler.

I agree with the answer above, "patronizing," or "condescending," and would add "dismissive," which might be a good alternative as it describes the same thing but without as much attitude attached. This means it might be a good word to use if you are trying to be diplomatic while still describing "patronizing and condescending." A fine point, but fine points are useful sometimes :)
