The phrase "puts down" can have a negative connotation, often used to describe derogatory or demeaning comments towards someone. To avoid this negative connotation, there are several synonyms that can be used instead. "Critiques" or "evaluates" could be used to provide constructive feedback, while "disagrees with" or "opposes" can be used to express a difference in opinion without insulting or belittling someone. "Rejects" or "dismisses" can be used to signify a disagreement with an idea or proposal, while "demeans" or "belittles" could be replaced with "disrespects" or "undermines". Choosing the appropriate synonym can make a significant difference in how a statement is received and perceived by others.
