I would say I enjoy their company for the most part but generally they can be a little too needy for me at times. And an INTP and NF shouldnt debate a topic that the NF feels strongly about because it'll just blow up in the intps face. Of the NFs Ive seen on different forums here, its the INFP that I sometimes clash most with. But I think its mostly because of insecurity and unhealthy INFP behavior, which I think can be legendary on the internets personality forums.
I like all feelers because they can bring a different perspective that I might not see to a discussion and I think that can be rather helpful. And they can be great healers when NTs are in emotional turmoil to sooth and heal the NT. Ive seen this before and have experienced it with an ENFP.
