Why 'especially bot lane'.
Bot lane is more forgivable if anything. There's the whole cooperative aspect. There could be multiple plays where you know you have the opportunity to get a couple kills back and your ally doesn't react to your play. So what should have been 2-0 turned in to 0-1 or 0-2 and you fall further behind.
Solo lanes? How the hell do you die in a solo lane outside of ganks? I mean, you know your opponent is there. You know what abilities they have, etc... Even dying once 1v1 is a clear mistake. Of course, everyone makes mistakes, but once you're 0-2 or 0-3 you should really have learned to just sit under tower. I can't even begin to count the number of games where I'm dominating bot lane and top or mid is falling so far behind (and the enemy solo laner has an XP advantage on me so they proceed to shut me down, then carry the game).
Just really tired of the polarity of all of these posts. Blaming bot lane explicitly for feeding. Anyone can feed, any role feeding is going to hurt your team. Dying in any situation while laning typically means you made a mistake. If you want to rant about it, at least include everyone.
