To find out that family tombstones were overturned a few years ago is one matter. To think that they could possibly be connected to a hate crime is another. The person who told me didn't specify "a few years ago", so I asked him or her and told him or her my concern. The tombstones were of some of my Irish family whom I will not specify right now, and of more-specific family within that family if my suspicions are correct.
If my suspicions are correct and the stones weren't overturned due to old age (and I don't know of their status now, though I assume that they've been returned upright), I will say this: regardless of whether someone found something out through anything I've written online, by figuring it themselves, etc., that gives them no right to do what they did. What they did also proves part of why certain family members chose to pass for fully Irish, and in a so-called "Christian" society.
That's why even on St. Patrick's Day and ever since I found out about my Jewish heritage, I identify as a Jew. While I'm also Irish among of other ethnic groups, I'm mostly Jewish. My father is a Jew, though he denies it. My mother is a Jew, although she denies it and is my parent of Irish descent. I'm a mostly-Patrilineal Jew and haven't forgotten that since almost 10 years ago, no matter how much any of my family members wants to deny that, and Saint Patrick didn't deny that the Jesus whose message was brought to him through my people (and the Irish people through him) was a Jew¹.
¹ Or as I believe, "Whose Message....Is a Jew".
