I think the most difficult thing in Islam, is that you have to reject many people. That is you don't accept them as good people but rather are evil destined to hell.
But the flip side of that, is because humanity has not united on guidance of God, the rebellious can be forcing accepting them or rejecting God. That is either accept them or reject God.
For example, a bisexual woman. You may see her as kind, cool, etc. However, they are when presenting themselves to be accepted, they are in indeed saying you should reject God's judgment on them and rather accept them.
This is not an easy decision either way. To reject Quran and guidance for a person is not easy. And to accept guidance and reject a person you care about is not easy as well.
This shows the importance of being sincere to truth. If Islam is false, it should not be followed. And if true it should be and people rejected instead.
We don't get to make up God per our whims just so that we can fit people in paradise.
