1. I never claimed philosophy was easier. The previous commenter blankly claimed the opposite
on the basis that they are a teacher. I am making a simple meta-observation that if they get to do that, then I get to claim I was literally born with philosophical tendencies in that such an ad hominem is entirely transparent except to the teacher. This argument itself is an example of rigorous, critical argumentation. If they get to use an ad hominem, then they break the rules of good faith argumentation, hence the whole illustrative point about people having philosophical personality traits.
2. The fact that you completely failed to read this exchange context carefully, such casual prejudice toward the argument from authority ("I am a teacher, take it from me, philosophy > math blah blah blah"), also raises doubt in the quality of actually existing philosophy education. It is a lot more like court philosopher behavior than any regard for close reading and actual research-level rigor.
3a. There's an objective, rational argument as to why philosophy is "hard" (emphasis on the quotes). A lot of it has to do with the fact that it is about speculatively complex questions. See for example Noam Chomsky's elaboration on this, he generally philosophy as a field as having deflationary characteristic in relation to scientific progress.
3b. What this also means is that "hardness" is not a good measure at all of a human discipline being actually a good discipline--astrology can also be very "hard", so can Derrida, etc. Simply writing a good piece of fiction is also cognitively hard. But where is this nuance, I ask you, in the OP comments? I do not see it. Where is the impact of philosophy, then?
All of these ought to part and parcel of students who actually learned philosophy well. The fact that multiple top comments do not evince this level of learning, at least on a tech social media forum, says a lot and it should trouble you.
(Having written all this, I think there is a further elaboration on 3a that makes the question/issue much more interesting, but it does not excuse the attitude of philosophy-chauvinism which is well known as thing in academia, analogous to how math/physics has their share of hardness chauvinists over other disciplines, ad infinitum.)
