This is a good practice, i appreciate what you’re doing. If anything, i occasionally like to respond to posts like that in order to set the record straight for other people who may read the comment. Debating or disproving the commenter isn’t necessary as much as putting correct information right there next to their bullshit. Some people might buy their lies or faux good-faith, but anyone on the fence or unsure will hopefully benefit from having the truth repeated right next to the lie/bs.
