Hey, trans person speaking. I appreciate the genuine attempt at understanding our issues and coming to a conclusion about it. I also want to say it's... really awful advice.
-Body Dysphoria is a mental disorder/suicide rates: Maybe you could classify it as such, but generally body dysphoria in that sense is within the context of false 'perceived' flaws that you hyper-focus on and will never be satisfied with regardless of any action you take. Like an anorexic having a distorted self-image of weight, to the degree that they retain dangerously low body-fat. Meanwhile, trans people after a successful transition will see their suicide rates
plummet way down relative to their fairly high initial rates pre-transition, and their general quality of life go up. It isn't a 'flaw' that we're forever trying to fix and unable to, it isn't looking in the mirror and forever hating what you are regardless of any changes you make. It's wanting to make a change, and then being satisfied after having done so. As an addendum, it's worth to note some trans people don't feel dysphoria at all: And only feel the so informally called 'body euphoria' as they make steps to transition.
-Dismantle 'Gender Roles': Here's something cool you might not know- not all trans people aim to be hyperfeminine/hypermasculine. In fact, there exist a number of nonbinary trans people who try to exist entirely outside of gender roles and yet still pursue a medical sex change. We're not all chasing a 'perfect' embodiment of a gender role, and even entirely
without gender roles I'm certain some of us would still exist(I probably would, considering I'm one of those people who isn't chasing after a gender role stereotype and didn't show 'any signs' of it.). The aesthetic values and reasons for transitioning all vary between. You incorrectly assume that gender transition is an attempt by an otherwise 'cisgender' person who mistakenly believes that taking actions related to the other gender role means that they should transition but... that's not at all what's happening. Just like it's fine for a cisgender male to present femininely, a transperson might actually enjoy and present the aesthetic values of their assigned-at-birth gender more. I know it's a bit confusing to cis people why we would pursue it
all if that's the case for some of us, the best I can say is it's the same reason you have a preference for some genders, or like a genre of music, or are interested in certain subjects. It's just the way some people... are.
"Just don't be trans lol": While I appreciate the genuine attempt at 'getting to love yourself the way you are.' Just. Don't. Please. We've tried. We've gone to therapists. We weigh the fallouts of being disowned by family and friends. We wonder if we can even pass as the other gender at all. We fear the ostracization and stigmatization in every relationship we'll ever have from now on. We've tried it. I've tried it. It doesn't work. Somethings are just nature, I'm not going to 'convert.' Sometimes we've wanted it, just to be 'normal.' Just so we wouldn't have to deal with this. Want to know why we have a high suicide date? As someone who's agonized over the reality we're faced with I can tell you - between the choice of never truly enjoying our life or forever being stigmatized, some of us decide it's just less painful to end it.
TL;DR: Your advice really boils down to the exact same advice that use to be given to non-heterosexuals with a new coat of paint. It's a very nice coat of paint that's trying very hard to be open and accepting, but it's still one that paints us as mentally-ill individuals who just can't be 'normal.'
