If you feel you've been harassed, you probably ought to bring it to the attention of forum moderators, as such behavior is addressed in the third point of the Acceptable Use Policy. You can do this easily by making use of the handy "Report" function that's made available at the top right of every single thread post. This action is much more appropriate than ambiguous accusations in open discussion.
That said, if you're looking for civil discussion, it's probably best to not equate someone requesting more information specific to the subject matter being discussed with someone who refuses to accept reasonable assertions as you did with the snarky "climate change denier" remark.
