I wouldn't say i'm soft, and i'm an INFP. Perhaps i'm more & more becoming an INFJ dichotomically, but my Fi and Ne are much stronger than Fe or Ni. I also think Fe users tend to be more soft than Fi users, i guess? Although Fe will easier notice mistakes in social handling than Fi whereas Fi will usually care less, and focus more on theirselves, and certainly correct less people, but sometimes they will project their values on others. I think Fi is much more focused than Fe which is more harmony-based.
I definitely have strong Ne. Perhaps i'm ENFP instead of INFP. It's a possibility. Or i'm INTP which some have suggested here as well. Some have suggested NFJ as well. I don't know. I guess INFP is middle-in-the-road between all types that have been suggested to me and it's what makes most sense to me right now.
But back to the topic, i'm known to be hard, both on the internet and here, and I sometimes don't shy away from confrontations or an argument. I can't stand "losing an argument", and I most certainly win most of them. But I only go into an argument if i care, like if my Fi-boundaries are broken, but they are easily broken to be honest, because my Fi is very demanding, extremely demanding and exhausting for myself. I generally set very high standards to myself and others. Also because I don't use Fe, i have less skill to comfort others, so even while I think I comfort people, i'm not known as someone who can comfort known, so that's why i'm seen as rather cold and hard, but than again i think i have good advice, have high conscience of what I do, what others do, and how I try to help others. I'm just not sure if i can communicate it well enough to others.
On some topics i come across as very soft and forgiving, but the way i talk about it might sound it hard again ironically, and that's the way with many things. I choose the softer side on debates, but i'm quite hard in bringing that over and making the arguments for it.
I'm harder though on the internet than in real-life i believe.
