I'm not really following the rap scene anymore, but why is Pusha T beefing with Weezy and Drake?
And yeah, Lil Wayne and Drake sucks.
You answered your own question in the bold

Because they are talentless hacks (atleast as MCs, Drake is decent producer) while thinking they are gods gift to Rap/hiphop music, trying to dismiss legends/veterans of the game as irrelevant because they sell more to teenie boopers, lol how delusional at potshots they had on Ludacris or Common etc (to make it clear, Common legend, Luda veteran). Drake (and Big Sean) said Luda is stealing their "flow"
Is part of the basic culture of MCing (battle rap), you dont question/diss others if you cant have nothing to offer as retort when they totally embarrass you and show you up as the talentless hack poser you are. Atleast Drake usually makes whiny pussy radio interviews, some diss songs, but usually just that. While Lil Wayne actually is deluded enough to try to reply and totally embarrass himself lol.
Here's lightweight level diss song by luda on Drake, yeah he didnt even need to put in much effort to embarrass Drake, who couldnt even reply to it lol:
Or simply respond to diss songs by saying "you are commercially successful" lol, yeah way to show your (lack of) skill level.
