I am not ignoring it, I am agreeing with it.

Agreed it needs more studying, but social media does does have influence, and its a reasonable assumption that that influence can be manipulated. It does definitely influence people who spend a lot of time on social media - they are very prone to believe conspiracy theories for example.
How effectively such manipulation can be varies and itself becomes a political issue. The PM of the UK recently implied that the Brexit vote was swayed by the Russians but was swiftly shot down (by members his own cabinet and the head of the internal intelligence service among others.).
