You can put the example of Switzerland. Swiss reintroduced lynxes already in the 1970s and have 50 years experience. Switzerland is a densely populated, industrialized West European country with no-nonsense people. They can give all the hard facts and personal experiences about things like why lynxes are not a danger to livestock farmers. You can ask conservationists, hikers, skiers, farmers, whomever.

I did not see a lynx this year, but seen just hours old footprints of a lynx walking on one of my favorite bicycle trails, right next to Basel. Lynxes live invisible, always picking places and times when people are not around. Funniest is that they are not even especially afraid of people and often travel on human roads. They simply are active at night, early dawn, evening, when people are not active. At the daytime they rest in thickets or rocks where people don't enter, but often very close to houses.
