You sound more comfortable with Ne, you art your blog. The write a lot. The fact you score INFJ on that buzzfeed quiz relating to more intuitive qualities than sensor is also a plus. I definitely think you have Ne and Si for sure. There is no question in that. I think you don't have Fe although you are a nice individual for sure.
Fi =/= douche bag.
You seem like you're strong in your emotions and are deeply in tune with them.
I mean if you want scientific, as Kierva said that's not my strong suit but chemistry is my guilty pleasure I hide from people.
Plus I don't think SJ's are that goofy to come out wearing an espeon costume in public. They're very much in keeping in check with their surroundings.
Plus many INFP's are homebodies. Imo, I think INFP's are the most sensor'ish intuitives.
