Its feels good to be helpful to others. Thats certainly what family and friends do for each other, if they have the capacity to do so.
Some thoughts on expressions of homophobia and transphobia. A person will often echo the words they hear in their social groups. If they think others are bigots, they will say similar things to fit in. This goes the other way to. If a person think they are in more open-minded group, they will often try to express similar sensibilities. The spoken words may seem disparaging or supportive, but neither may give a true picture of what they actually would do if they learned that a friend or relative was trans.
Humans are complicated.
