The natives of Aries are often very confident and quick-to-action people, who may not do well when the moon is in a contemplative house like Libra. Your tendency to charge into things often works well when you're trying to accomplish a task, but if you present your hot-take on an argument without a second thought you may find yourself on unsure ground as the discussion commences.
Natives of Taurus have little business doing the work of a Libra. Fortunately you are one of the signs that is least likely to impose views on others. Wait for others to ask you to join debates. Your stubbornness may make you a poor moderator, but if you feel you are in the right do not be afraid to stand your ground.
Cancerians should be careful not to take arguments personally. Due to the natures of both your sign, and the moon in Libra, you are likely to find yourself in the middle of many issues today. While many people view moderation as a soft ideology, the people in the middle are often fought on both sides. All that you can do is argue for your position, rather than arguing against everyone else's. This will prove both safer, and more convincing.
Natives of Gemini are not often known for their quick wit, but it is a characteristic of this sign none the less. Consider intervening in arguments as seldom as possible taking the time in between to develop your responses. With a little thought and a lot of intuition you should be able to steer a conversation with little wasted breath.
Leos can make the best of this day, or they can ruin it for everyone. Some natives of Leo are primarily interested in helping others, and these people will do excellent things today. Other Leos are largely interested in others' perceptions of them, and these people are more likely to take arguments against their stance as arguments against themselves and fall down a slippery slope to petty grievances. If you are the first kind of Leo, speak well. If you are the second kind of Leo, speak seldom.
Virgoans are not likely to have trouble being intrusive into other peoples' affairs, and may consider weighing their own actions on the balance. Few people likely keep close tabs on you, as you are a hard-worker, and due to your private nature it is difficult for peers to know what you are up to and offer criticism. This is a dangerous recipe for run-away ethics.
Librans should look at today not as a day of competition, but one of conversation. On the most hectic of days you often find yourself wishing that everyone was more like you, and today they are, so rather than feeling threatened, revel in every viewpoint you hear today, regardless of how far they may differ from yours. This is a potentially rewarding educational opportunity.
While it is unwise for Scorpios to use your tails today, you should remind yourselves that you are venomous creatures not to be trod upon. If you devote less energy into attacking your opponent and more into destroying their argument, you are likely to find yourselves to be highly successful debaters. You just can't let that temper get the best of you.
Sagittarians may want to take some time off today to think about their own lives. The world is likely to seem a rather high-energy place today, and while this is an environment that you can handle yourselves in, you would likely find more happiness and more meaningful thought in the peacefulness of the wilderness.
Capricorns are often interested in proving their worth in the workplace, and a lot of Libra qualities are highly sought after. Consider stepping out of your door and engaging in arguments to see if you can't get the respect of your peers by collecting a few talking points.
Natives of Aquarius are seldom moderates, which makes you interesting people with the moon in Libra, as your personal scale is usually weighted to one end or the other. While you could try to adjust this and make arguments from the middle, it would likely be more useful for you to make your own arguments as counters to others, not to prove that you are right, but to narrate how many ways an idea can be taken.
Children of Pisces make excellent Libras. Your characteristic inability to make up your minds comes from a deep understanding of people and the world around you. All that you have to do to exist in today's astrological landscape is express your views. Consider narrating your thoughts as they come to you, as this will likely help others understand your insight.
