1) You're equivocating checking every illegal immigrant crossing the southern border for a disease that has no evidence of existing in their country to checking people at legal ports of entry for an outbreak in the area they are traveling directly from. You think those are similar enough for your whataboutism.
2) We know for a fact that nobody traveled from Africa through Mexico and infected any American with ebola, showing that any additional resources spent to prevent that would've been wasted.
3) I don't think anybody on here eve argued against testing at the Southern border for ebola so I don't know what "you guys" you were referring to, but I guess they're right.
You just got defeated by your own straw man.
