First of all don't be offended by the title I just thought it was funny.
F people creep me out. I don't understand them. I see making decisions off of your feelings as selfish and irrisponsible. The worst excuse ever, "I felt like it", like that matters. If people justify their actions according to their feelings where is the line that says what you were feeling is wrong. It seems immature. How is putting your feelings on someone else productive to anything? Where is the self control? You cant argue against what someone is feeling and asking someone to take your feelings into account is like asking them to cater unobjectively to you.
I am not trying to make people mad here I am trying to understand. What makes you all tick?
There is no rationality behind this.
They simply do what they feel is right. Fs with a well developed T however, are slightly different. They are value driven, but not ruled by their feelings. Unlike Ts, they prefer not to make decisions based on what appears to be of highest utility to the given situation (though they could because of their proficiency with thinking), but rather envision their ideal self. They then use logic to make sure they are as in tune with that self as possible.
This is irresponsible in the regard that it has the potential ignores the many important aspects of the current situation which may be irrelevant to their personal quest for the ideal self. This kind of decision making is most common among INFJs, the most Thinking oriented of NFs. This may be irresponsible, but not nearly as much as the behavior of hard-core Fs, theirs is altogether whimsical.
However, the only thing Feelers without a well developed Thinking function could say is that their Feelings are valid and thats period. Must do as they feel no matter what.
Is this a good idea? They are not concerned, as one needs thinking faculties to critically examine such a question. They by default assume it is a good idea in order to give affirmation to their feelings.
Sorry about your break up with a F'er. Yes, most logical thing is to swear off feelers for life and paint them with the broad brush of everything that went wrong with your lover. lol. I done the same thing years ago about thinkers without realizing then the difference between thinker and feelers in mbti terms.
For the sake of this discussion. Lets assume that the OP was inspired by a bad experience with an F. Just like you once were led to have negative feelings about Ts due to bad experiences with them.
In your case, it was only an emotional reaction.
In this case, it is an emotional reaction, but not only that. It is also an argument for the existence of the vices of Feelers mentioned in the OP.
The emotional reaction bit is irrelevant. What is relevant is whether or not the statement made is true. Above we see an argument for why making decisions based on Feelings is irresponsible. We have not yet seen an argument for the vices of Thinkers from you.
For this reason, we cannot hold the two claims side by side.
