Is the following prescriptive and/or invalidating?

I was discussing something with a person, and told them why i dont like something, and explained why i dont like it, without telling anyone else to dislike or like it, as i didnt intend to impose on anyone else. But in response to my explanation, the person said "you shouldnt dislike it for that reason, and i think it is illogical and stupid to not like it for that reason", and in response i told them that they were being prescriptive and invalidating, something i was not, and wished i could be shown the same courtesy, but in response they said that, since they were saying "i think", and presenting it as an opinion and belief, rather than an objective fact, that what they said was not being prescriptive nor invalidating. so i would like to ask you all what is your assessment of this.
