How about we look at the verses in their entirety?
Lets take the Mk 4 passage: "God has been given to you. But to those on the outside everything is said in parables 12 so that, " 'they may be ever seeing but never perceiving, and ever hearing but never understanding; otherwise they might turn and be forgiven!' "
You left out the embolden part because it shows what may have happened IF indeed he didn't speak to them in parables, something that would be IMPOSSIBLE if they were born Totally blind and unable to believe without the prior work of regeneration.
What is really happening here? Jesus has preselected a few from Israel to be his apostles, to take the message of redemption to the rest of the world. The rest of Israel is being temporarily blinded to keep them in the darkness so they will crucify him thus fulfilling the prophecy and providing atonement for the world. It is ONLY after He is raised up (crucified and resurrected) that he draws all men to himself (sends the Spirit, and the gospel into all the world) thus beginning the His church....built on the rock of his appointed and inspired messengers (those on the inside that are being given to know these things).
No Arminian worth his salt would deny this truth. This is a problem for Calvinists, not Arminians.
