I gave reasons why Jon and Gendry have no claim the Iron Throne.
You come in here talking about how the Lannisters didn't have to prove anything.
I explain to you why they didn't need to prove anything and now you're in here talking about taking the crown through force?
The Lannisters didn't take the crown by force.
Neither Jon nor (especially) Gendry have the means to take it by force.
So... the hell are you talking about?


Even Robert Baratheon, the person who actually did take the crown by force had to justify it through his bloodline. His grandmother was a Targaryen and that was necessary to consolidate his power as King. Rhaegar was his cousin.
