|Going Viking is frowned upon in modern society|
As such, we as Ásatrúar are faced with the problem of what to do when we find our religious beliefs and practices conflict with the expectations and requirements of modern society. There are three possible courses of action in such cases: 1) abandon the questionable item, 2) modify the questionable item, and 3) retain the questionable item and face the consequences and pressures that may result.
Not only are most modern people ill-equipped to perform the ritual (unlike in ancient days, when more rural lifestyles meant many more people were familiar with the basics of killing and dressing livestock), but social pressure against doing so is enormous. In some jurisdictions there are also legal obstacles that need to be overcome (although the US Supreme Court has ruled in Church of the Lukumi Babalu Aye, Inc. v. Hialeah (1993) that animal sacrifice is a protected form of religious expression under the First Amendment to the Constitution).
For myself, I tend to want to lean in favor of reconstructing the elder practices, and the desires of modern society be damned. Unless there are clear-cut legal prohibitions (such as the case of human sacrifice), I am of the school that holds that part of Ásatrú is the attempt to recreate the ancient pre-Christian Heathen mindset. And part of that effort means that modern mores (whether they be neo-liberal "social justice" or neo-Victorian social conservatism) must take a back seat to the ancient beliefs of our ancestors. This doesn’t mean I am against all innovation or change, but I think to immediately jump to change, without even giving the elder practices a chance to work in practical terms, is a mistake. Those ancient practices and beliefs were born of hundreds of generations of trial-and-error, and to turn our backs on that source of collected experience and wisdom seems unwise at best.
