And the implication is fairly strong. The Elven King may well be paranoid, especially concerning Dwarves, especially regarding Thingol though this movie more than implies (and even the book does) that he'd had some dealings with them and with outsiders since, certainly in the long years since the ruin of Doriath. And Thranduil's realm was never guarded by a Girdle like that of Melian The Maia.
Forgive me. I meant of course that it is implied, and from the implication it can be inferred.
He also had dealings frequently enough with The Men of Long Lake. Also, it is one thing to be paranoid about dwarves, but Gandalf at least was a known entity, beloved amongst The Elves. That they were willing to take Gollum into their keeping at his askance suggests a great deal of respect and fondness for him, and more than he likely built up by great deeds and aid in the singular Battle of Five Armies, significant as that aid was.
His words to Gandalf in the Hobbit are not really what one would expect him to use regarding a new acquaintaince. To compare his relation to Thorin and company to his relationship to one of The Five Wiazards, the one most revered and loved amongst The Elves no less, is a grave mistake. Legolas was deeply grieved by the fall of Gandalf, and that is fat more than would be expected by an Elf towards a figure whom they had only met once or twice in passing.
Greenwood is where the Shadow of Sauron returning first fell. It is where Gandalf's eye would have been drawn to very early after his arrival from Valinor. Really, I am surprised at even the suggestion that, at the late date in the Third Age Timeline which the events of this tale belong to, Gandalf The Gray, who had been close in friendship with The Elves in this incarnation for over two Thousand years by this point, would not have at least been acquainted with Thranduil. And I am certain he would have, even if unenlightned, been curious about this Wanderer who looked like an old man, but who diminished not with the passing of time, and worked wonders, and who was so reverently received and respected by the likes of Cirdan, Galadriel, Elrond and Glorfindel. Even with his potential resentments of Galadriel, he would want to know this intriguing person and would also not want to be shown up as a host by his kin. Gandalf went everywhere in The North and West, and I do not think Thranduil would have lightly shut his doors in his face. As Bilbo considered when measuring the polite pace of closing his own door, "Wizards, after all, are Wizards."
However, you are still using the word infer improperly.
The reason why I believe that the Elvenking is paranoid about allowing outsiders into his realm is because of the fate of Thingol (his relation) and his own realm, which was destroyed by Dwarves. Then there was the death of Thranduil's father Oropher at the Battle of Dagorlad. After that, he seemed to feel that the outside world was good for trade, but little else.
"Hear me, hounds of Sauron, Gandalf is here! Fly if you value your foul skins, I will shrivel you from tail to snout if you step within this circle!"
"Do not be to eager to deal out death in judgement. Even the very wise cannot see all ends."
