I was reading an excerpt from this
[book](https://www.amazon.co.jp/%E5%85%A8%E6%80%9D%E8%80%83-%E5%B9%BB%E5%86%AC%E8%88%8E%E6%96%87%E5%BA%AB-%E5%8C%97%E9%87%8E-%E6%AD%A6/dp/4344412869)
and it read something like this:

> 物体は激しく動けば、それだけ摩擦が大きくなる。人間 **だって**
> 、激しく動くと熱を持つのだ。端から見れば、輝いている人間のことが、きっと羨ましく見えるのだろう。
>
> だけど、輝いている本人は熱くてたまらないのだ。(中略)
>
> これは真面目に、けっこう辛いことなのだ。
>
> **カッコつけている** わけじゃない。自分がそうなってみて、実感としてそう感じる。

Here are my questions:

  1. `だって` is just `でも`, similar to the one explained [here](https://japanese.stackexchange.com/a/77676/29327), right?
  2. What is the 主語 of the sentence`カッコつけている`わけじゃない。I would translate it as "It's not that I'm showing off (here). Even if I (myself) become like that (i.e., 輝いている本人), I would/will feel the same (i.e., けっこう辛い)." I don't understand it because the author doesn't seem to be showing off or being pretentious. Or am I not noticing something?

P.S.: I can remove the 「中略」 if you think it's necessary to finding the 主語.

Understanding 北野武 「全思考」
1. Yes, this だって is like "also" or "even".
  2. The subject of カッコつけている is 輝いている人 in general. Here 格好付け refers to saying 辛い ("I'm suffering") even though they objectively seem highly successful and happy. The author thinks a successful celebrity saying such a thing may seem pretentious or contrived, but he is saying that the pain successful people are feeling is a real one, not a feigned one.
