As someone who has been hurt and traumatized a lot by toxic masculinity in real life, I cannot express how much the men in Tolkien's legendarium mean to me (there are many examples I could cite, but I'm going to stick to a few that mean the most to me personally and also don't get talked about as much).
I love how Manwë's first reaction is never anger. He is the Elder King, King of the Valar, King of Arda and he's not afraid to cry in public, to be worried and saddened and therefore show "weakness" instead of fluffing up big time and being angry just so he can pretend to be The Man. He's compassionate and believes in the good in people even when he shouldn't.
I love how Ulmo decided to help those he cared about, even if the people in question were not perfect to say the least and officially he was not supposed to be helping at all. He is neither afraid nor ashamed to care.
I love how excited Aulë was for the arrival of the Children (so much so that he made his own), how much joy he finds in teaching and being creative with others instead of wanting to be The Best At Everything and how he speaks up for other creatives too, trying to help others understand their mindset.
I love how polite and warm Eönwë is, giving a rather cordial greeting to someone who was technically trespassing in his home. He's a hero to me not because a line was included that he's the best warrior Maia, but because he's kind and wise, sparing Maedhros and Maglor because he knew the senseless violence had to end. And yes, I also love how old lore Fionwë was crushing on Arien/Urwendi.
So yeah, just some examples, but these are among the ones that stuck with me.
